Given numbers are 402, 786, 436, 979

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

Apply this formula for all numbers.

Step1:

LCM(402, 786) = 52662

GCD(402, 786) = ( 402 x 786 ) / 52662

= 402 / 786

= 402

Step2:

LCM(6, 436) = 1308

GCD(6, 436) = ( 6 x 436 ) / 1308

= 6 / 436

= 6

Step3:

LCM(2, 979) = 1958

GCD(2, 979) = ( 2 x 979 ) / 1958

= 2 / 979

= 2

So, Greatest Common Divisor of 402, 786, 436, 979 is 1
