Question

find the HCF and LCM of 81, 99 and 30​

Answer 1

Answer:

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 99, 30 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 81, 99, 30 is 3 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 81, 99, 30 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 where 0 ≤ r ≤ b

Highest common factor (HCF) of 81, 99, 30 is 3.

HCF(81, 99, 30) = 3
