Given numbers are 712, 688, 784, 139

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

Apply this formula for all numbers.

Step1:

LCM(712, 688) = 61232

GCD(712, 688) = ( 712 x 688 ) / 61232

= 712 / 688

= 712

Step2:

LCM(8, 784) = 784

GCD(8, 784) = ( 8 x 784 ) / 784

= 8 / 784

= 8

Step3:

LCM(8, 139) = 1112

GCD(8, 139) = ( 8 x 139 ) / 1112

= 8 / 139

= 8

So, Greatest Common Divisor of 712, 688, 784, 139 is 1
