Given numbers are 915, 490, 798, 870

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

Apply this formula for all numbers.

Step1:

LCM(915, 490) = 89670

GCD(915, 490) = ( 915 x 490 ) / 89670

= 915 / 490

= 915

Step2:

LCM(5, 798) = 3990

GCD(5, 798) = ( 5 x 798 ) / 3990

= 5 / 798

= 5

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 915, 490, 798, 870 is 1
