GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(874, 870) = 380190
GCD(874, 870) = ( 874 x 870 ) / 380190
= 874 / 870
= 874
Step2:
LCM(2, 915) = 1830
GCD(2, 915) = ( 2 x 915 ) / 1830
= 2 / 915
= 2
So, Greatest Common Divisor of 874, 870, 915 is 1
