GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 412) = 406644
GCD(987, 412) = ( 987 x 412 ) / 406644
= 987 / 412
= 987
Step2:
LCM(1, 576) = 576
GCD(1, 576) = ( 1 x 576 ) / 576
= 1 / 576
= 1
Step3:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
So, Greatest Common Divisor of 987, 412, 576, 931 is 1
