Given numbers are 621, 522, 977, 180
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 522) = 36018
GCD(621, 522) = ( 621 x 522 ) / 36018
= 621 / 522
= 621
Step2:
LCM(9, 977) = 8793
GCD(9, 977) = ( 9 x 977 ) / 8793
= 9 / 977
= 9
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 621, 522, 977, 180 is 1
