Given numbers are 645, 515, 948, 734

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

Apply this formula for all numbers.

Step1:

LCM(645, 515) = 66435

GCD(645, 515) = ( 645 x 515 ) / 66435

= 645 / 515

= 645

Step2:

LCM(5, 948) = 4740

GCD(5, 948) = ( 5 x 948 ) / 4740

= 5 / 948

= 5

Step3:

LCM(1, 734) = 734

GCD(1, 734) = ( 1 x 734 ) / 734

= 1 / 734

= 1

So, Greatest Common Divisor of 645, 515, 948, 734 is 1
