Given numbers are 960, 125, 255, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(960, 125) = 24000
GCD(960, 125) = ( 960 x 125 ) / 24000
= 960 / 125
= 960
Step2:
LCM(5, 255) = 255
GCD(5, 255) = ( 5 x 255 ) / 255
= 5 / 255
= 5
Step3:
LCM(5, 643) = 3215
GCD(5, 643) = ( 5 x 643 ) / 3215
= 5 / 643
= 5
So, Greatest Common Divisor of 960, 125, 255, 643 is 1
