Steps to Calculate GCD of 52, 80, 99, 21 using LCM Formula
Given numbers are 52, 80, 99, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(52, 80) = 1040
GCD(52, 80) = ( 52 x 80 ) / 1040
= 52 / 80
= 52
Step2:
LCM(4, 99) = 396
GCD(4, 99) = ( 4 x 99 ) / 396
= 4 / 99
= 4
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 52, 80, 99, 21 is 1
