Given numbers are 312, 780, 875
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 780) = 1560
GCD(312, 780) = ( 312 x 780 ) / 1560
= 312 / 780
= 312
Step2:
LCM(156, 875) = 136500
GCD(156, 875) = ( 156 x 875 ) / 136500
= 156 / 875
= 156
So, Greatest Common Divisor of 312, 780, 875 is 1
