Given numbers are 974, 221, 400, 931
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(974, 221) = 215254
GCD(974, 221) = ( 974 x 221 ) / 215254
= 974 / 221
= 974
Step2:
LCM(1, 400) = 400
GCD(1, 400) = ( 1 x 400 ) / 400
= 1 / 400
= 1
Step3:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
So, Greatest Common Divisor of 974, 221, 400, 931 is 1
