Given numbers are 747, 621, 778, 124

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

Apply this formula for all numbers.

Step1:

LCM(747, 621) = 51543

GCD(747, 621) = ( 747 x 621 ) / 51543

= 747 / 621

= 747

Step2:

LCM(9, 778) = 7002

GCD(9, 778) = ( 9 x 778 ) / 7002

= 9 / 778

= 9

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 747, 621, 778, 124 is 1
