Given numbers are 870, 921, 688, 626
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 921) = 267090
GCD(870, 921) = ( 870 x 921 ) / 267090
= 870 / 921
= 870
Step2:
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
= 3 / 688
= 3
Step3:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
So, Greatest Common Divisor of 870, 921, 688, 626 is 1
