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

Apply this formula for all numbers.

Step1:

LCM(784, 720) = 35280

GCD(784, 720) = ( 784 x 720 ) / 35280

= 784 / 720

= 784


Step2:

LCM(16, 738) = 5904

GCD(16, 738) = ( 16 x 738 ) / 5904

= 16 / 738

= 16


Step3:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2
