Given numbers are 747, 606, 391, 509

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

Apply this formula for all numbers.

Step1:

LCM(747, 606) = 150894

GCD(747, 606) = ( 747 x 606 ) / 150894

= 747 / 606

= 747

Step2:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 747, 606, 391, 509 is 1
