GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 757) = 300529
GCD(397, 757) = ( 397 x 757 ) / 300529
= 397 / 757
= 397
Step2:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 397, 757, 887, 689 is 1
