GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 765) = 9945
GCD(195, 765) = ( 195 x 765 ) / 9945
= 195 / 765
= 195
Step2:
LCM(15, 870) = 870
GCD(15, 870) = ( 15 x 870 ) / 870
= 15 / 870
= 15
Step3:
LCM(15, 765) = 765
GCD(15, 765) = ( 15 x 765 ) / 765
= 15 / 765
= 15
So, Greatest Common Divisor of 195, 765, 870, 765 is 15
