Given numbers are 555, 155, 641, 916
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 155) = 17205
GCD(555, 155) = ( 555 x 155 ) / 17205
= 555 / 155
= 555
Step2:
LCM(5, 641) = 3205
GCD(5, 641) = ( 5 x 641 ) / 3205
= 5 / 641
= 5
Step3:
LCM(1, 916) = 916
GCD(1, 916) = ( 1 x 916 ) / 916
= 1 / 916
= 1
So, Greatest Common Divisor of 555, 155, 641, 916 is 1
