Given numbers are 845, 377, 253, 642

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

Apply this formula for all numbers.

Step1:

LCM(845, 377) = 24505

GCD(845, 377) = ( 845 x 377 ) / 24505

= 845 / 377

= 845

Step2:

LCM(13, 253) = 3289

GCD(13, 253) = ( 13 x 253 ) / 3289

= 13 / 253

= 13

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 845, 377, 253, 642 is 1
