Given numbers are 945, 873, 640, 353

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

Apply this formula for all numbers.

Step1:

LCM(945, 873) = 91665

GCD(945, 873) = ( 945 x 873 ) / 91665

= 945 / 873

= 945

Step2:

LCM(9, 640) = 5760

GCD(9, 640) = ( 9 x 640 ) / 5760

= 9 / 640

= 9

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 945, 873, 640, 353 is 1
