Given numbers are 637, 357, 402, 394

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

Apply this formula for all numbers.

Step1:

LCM(637, 357) = 32487

GCD(637, 357) = ( 637 x 357 ) / 32487

= 637 / 357

= 637

Step2:

LCM(7, 402) = 2814

GCD(7, 402) = ( 7 x 402 ) / 2814

= 7 / 402

= 7

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 637, 357, 402, 394 is 1
