Given numbers are 415, 255, 916, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 255) = 21165
GCD(415, 255) = ( 415 x 255 ) / 21165
= 415 / 255
= 415
Step2:
LCM(5, 916) = 4580
GCD(5, 916) = ( 5 x 916 ) / 4580
= 5 / 916
= 5
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 415, 255, 916, 643 is 1
