Steps to Calculate GCD of 58, 42, 57, 21 using LCM Formula
Given numbers are 58, 42, 57, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(58, 42) = 1218
GCD(58, 42) = ( 58 x 42 ) / 1218
= 58 / 42
= 58
Step2:
LCM(2, 57) = 114
GCD(2, 57) = ( 2 x 57 ) / 114
= 2 / 57
= 2
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 58, 42, 57, 21 is 1
