Given numbers are 155, 130, 493, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 130) = 4030
GCD(155, 130) = ( 155 x 130 ) / 4030
= 155 / 130
= 155
Step2:
LCM(5, 493) = 2465
GCD(5, 493) = ( 5 x 493 ) / 2465
= 5 / 493
= 5
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 155, 130, 493, 641 is 1
