Given numbers are 847, 763, 977, 690

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(847, 763) = 92323

GCD(847, 763) = ( 847 x 763 ) / 92323

= 847 / 763

= 847

Step2:

LCM(7, 977) = 6839

GCD(7, 977) = ( 7 x 977 ) / 6839

= 7 / 977

= 7

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 847, 763, 977, 690 is 1
