Given numbers are 556, 151, 956, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 151) = 83956
GCD(556, 151) = ( 556 x 151 ) / 83956
= 556 / 151
= 556
Step2:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 556, 151, 956, 420 is 1
