WebThe product of HCF and LCM of given numbers is always equal to the product of the two numbers. If a and b are two given positive numbers, then a x b = HCF (a, b) x LCM (a, b) Proof: If 8 and 10 are two numbers substitute a and b with 8 and 10 in an above-mentioned equation, we get. 8 x 10 = HCF (8, 10) x LCM (8, 10) WebApr 5, 2024 · To find the HCF, we list the common prime factor and their smallest exponents in 90 and 144 as under: Common prime factor = 2, 3 Least exponents that is the least amount of power we have = 1, 2 HCF = 2 1 × 3 2 = 9 x 2 = 18 To find LCM we have to make a list of all prime factors of 90 and 144, their greatest exponents as follows:

WebThe full form of HCF in Maths is Highest Common Factor. As the rules of mathematics dictate, the greatest common divisor or the gcd of two or more positive integers happens to be the largest positive integer that divides the numbers without leaving a remainder. For example, take 8 and 12. The H.C.F. of 8 and 12 will be 4 because the highest ... WebHCF of 1800, 270 is 90 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example. Consider we have numbers 1800, 270 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r ... psat vitamin
