GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 436) = 3924
GCD(981, 436) = ( 981 x 436 ) / 3924
= 981 / 436
= 981
Step2:
LCM(109, 415) = 45235
GCD(109, 415) = ( 109 x 415 ) / 45235
= 109 / 415
= 109
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 981, 436, 415, 256 is 1
