Given numbers are 646, 139, 103, 632

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

Apply this formula for all numbers.

Step1:

LCM(646, 139) = 89794

GCD(646, 139) = ( 646 x 139 ) / 89794

= 646 / 139

= 646

Step2:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

Step3:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

So, Greatest Common Divisor of 646, 139, 103, 632 is 1
