GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 987) = 252672
GCD(768, 987) = ( 768 x 987 ) / 252672
= 768 / 987
= 768
Step2:
LCM(3, 174) = 174
GCD(3, 174) = ( 3 x 174 ) / 174
= 3 / 174
= 3
Step3:
LCM(3, 915) = 915
GCD(3, 915) = ( 3 x 915 ) / 915
= 3 / 915
= 3
So, Greatest Common Divisor of 768, 987, 174, 915 is 3
