Steps to Calculate GCD of 62, 21, 99, 42 using LCM Formula
Given numbers are 62, 21, 99, 42
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(62, 21) = 1302
GCD(62, 21) = ( 62 x 21 ) / 1302
= 62 / 21
= 62
Step2:
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
= 1 / 99
= 1
Step3:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
So, Greatest Common Divisor of 62, 21, 99, 42 is 1
