Given numbers are 255, 770, 561, 416
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 770) = 39270
GCD(255, 770) = ( 255 x 770 ) / 39270
= 255 / 770
= 255
Step2:
LCM(5, 561) = 2805
GCD(5, 561) = ( 5 x 561 ) / 2805
= 5 / 561
= 5
Step3:
LCM(1, 416) = 416
GCD(1, 416) = ( 1 x 416 ) / 416
= 1 / 416
= 1
So, Greatest Common Divisor of 255, 770, 561, 416 is 1
