Given numbers are 556, 495, 802, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 495) = 275220
GCD(556, 495) = ( 556 x 495 ) / 275220
= 556 / 495
= 556
Step2:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 556, 495, 802, 561 is 1
