Given numbers are 556, 764, 220, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 764) = 106196
GCD(556, 764) = ( 556 x 764 ) / 106196
= 556 / 764
= 556
Step2:
LCM(4, 220) = 220
GCD(4, 220) = ( 4 x 220 ) / 220
= 4 / 220
= 4
Step3:
LCM(4, 687) = 2748
GCD(4, 687) = ( 4 x 687 ) / 2748
= 4 / 687
= 4
So, Greatest Common Divisor of 556, 764, 220, 687 is 1
