Steps to Calculate GCD of 50, 95, 98, 21 using LCM Formula
Given numbers are 50, 95, 98, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(50, 95) = 950
GCD(50, 95) = ( 50 x 95 ) / 950
= 50 / 95
= 50
Step2:
LCM(5, 98) = 490
GCD(5, 98) = ( 5 x 98 ) / 490
= 5 / 98
= 5
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 50, 95, 98, 21 is 1
