Steps to Calculate GCD of 58, 63, 21, 58 using LCM Formula
Given numbers are 58, 63, 21, 58
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(58, 63) = 3654
GCD(58, 63) = ( 58 x 63 ) / 3654
= 58 / 63
= 58
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 58) = 58
GCD(1, 58) = ( 1 x 58 ) / 58
= 1 / 58
= 1
So, Greatest Common Divisor of 58, 63, 21, 58 is 1
