Given numbers are 974, 646, 421, 568
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(974, 646) = 314602
GCD(974, 646) = ( 974 x 646 ) / 314602
= 974 / 646
= 974
Step2:
LCM(2, 421) = 842
GCD(2, 421) = ( 2 x 421 ) / 842
= 2 / 421
= 2
Step3:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
So, Greatest Common Divisor of 974, 646, 421, 568 is 1
