Given numbers are 915, 870, 178, 347

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

Apply this formula for all numbers.

Step1:

LCM(915, 870) = 53070

GCD(915, 870) = ( 915 x 870 ) / 53070

= 915 / 870

= 915

Step2:

LCM(15, 178) = 2670

GCD(15, 178) = ( 15 x 178 ) / 2670

= 15 / 178

= 15

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 915, 870, 178, 347 is 1
