Given numbers are 747, 783, 383, 621

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

Apply this formula for all numbers.

Step1:

LCM(747, 783) = 64989

GCD(747, 783) = ( 747 x 783 ) / 64989

= 747 / 783

= 747

Step2:

LCM(9, 383) = 3447

GCD(9, 383) = ( 9 x 383 ) / 3447

= 9 / 383

= 9

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 747, 783, 383, 621 is 1
