Given numbers are 981, 640, 136, 424
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 640) = 627840
GCD(981, 640) = ( 981 x 640 ) / 627840
= 981 / 640
= 981
Step2:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
Step3:
LCM(1, 424) = 424
GCD(1, 424) = ( 1 x 424 ) / 424
= 1 / 424
= 1
So, Greatest Common Divisor of 981, 640, 136, 424 is 1
