GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(994, 868) = 61628
GCD(994, 868) = ( 994 x 868 ) / 61628
= 994 / 868
= 994
Step2:
LCM(14, 643) = 9002
GCD(14, 643) = ( 14 x 643 ) / 9002
= 14 / 643
= 14
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 994, 868, 643, 665 is 1
