Given numbers are 645, 842, 363, 751

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

Apply this formula for all numbers.

Step1:

LCM(645, 842) = 543090

GCD(645, 842) = ( 645 x 842 ) / 543090

= 645 / 842

= 645

Step2:

LCM(1, 363) = 363

GCD(1, 363) = ( 1 x 363 ) / 363

= 1 / 363

= 1

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 645, 842, 363, 751 is 1
