Given numbers are 621, 783, 107, 747

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

Apply this formula for all numbers.

Step1:

LCM(621, 783) = 18009

GCD(621, 783) = ( 621 x 783 ) / 18009

= 621 / 783

= 621

Step2:

LCM(27, 107) = 2889

GCD(27, 107) = ( 27 x 107 ) / 2889

= 27 / 107

= 27

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 621, 783, 107, 747 is 1
