Given numbers are 915, 640, 744, 830

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

Apply this formula for all numbers.

Step1:

LCM(915, 640) = 117120

GCD(915, 640) = ( 915 x 640 ) / 117120

= 915 / 640

= 915

Step2:

LCM(5, 744) = 3720

GCD(5, 744) = ( 5 x 744 ) / 3720

= 5 / 744

= 5

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 915, 640, 744, 830 is 1
