Given numbers are 782, 870, 79, 354

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

Apply this formula for all numbers.

Step1:

LCM(782, 870) = 340170

GCD(782, 870) = ( 782 x 870 ) / 340170

= 782 / 870

= 782

Step2:

LCM(2, 79) = 158

GCD(2, 79) = ( 2 x 79 ) / 158

= 2 / 79

= 2

Step3:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

So, Greatest Common Divisor of 782, 870, 79, 354 is 1
