Given numbers are 786, 402, 688, 210

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

Apply this formula for all numbers.

Step1:

LCM(786, 402) = 52662

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

= 786 / 402

= 786

Step2:

LCM(6, 688) = 2064

GCD(6, 688) = ( 6 x 688 ) / 2064

= 6 / 688

= 6

Step3:

LCM(2, 210) = 210

GCD(2, 210) = ( 2 x 210 ) / 210

= 2 / 210

= 2

So, Greatest Common Divisor of 786, 402, 688, 210 is 2
