Given numbers are 634, 689, 20, 383

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

Apply this formula for all numbers.

Step1:

LCM(634, 689) = 436826

GCD(634, 689) = ( 634 x 689 ) / 436826

= 634 / 689

= 634

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 634, 689, 20, 383 is 1
