Given numbers are 747, 669, 798, 988

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

Apply this formula for all numbers.

Step1:

LCM(747, 669) = 166581

GCD(747, 669) = ( 747 x 669 ) / 166581

= 747 / 669

= 747

Step2:

LCM(3, 798) = 798

GCD(3, 798) = ( 3 x 798 ) / 798

= 3 / 798

= 3

Step3:

LCM(3, 988) = 2964

GCD(3, 988) = ( 3 x 988 ) / 2964

= 3 / 988

= 3

So, Greatest Common Divisor of 747, 669, 798, 988 is 1
