Given numbers are 784, 670, 280, 880

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

Apply this formula for all numbers.

Step1:

LCM(784, 670) = 262640

GCD(784, 670) = ( 784 x 670 ) / 262640

= 784 / 670

= 784

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

Step3:

LCM(2, 880) = 880

GCD(2, 880) = ( 2 x 880 ) / 880

= 2 / 880

= 2

So, Greatest Common Divisor of 784, 670, 280, 880 is 2
