GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 874) = 37582
GCD(989, 874) = ( 989 x 874 ) / 37582
= 989 / 874
= 989
Step2:
LCM(23, 892) = 20516
GCD(23, 892) = ( 23 x 892 ) / 20516
= 23 / 892
= 23
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 989, 874, 892, 645 is 1
