Given numbers are 678, 312, 750, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 312) = 35256
GCD(678, 312) = ( 678 x 312 ) / 35256
= 678 / 312
= 678
Step2:
LCM(6, 750) = 750
GCD(6, 750) = ( 6 x 750 ) / 750
= 6 / 750
= 6
Step3:
LCM(6, 515) = 3090
GCD(6, 515) = ( 6 x 515 ) / 3090
= 6 / 515
= 6
So, Greatest Common Divisor of 678, 312, 750, 515 is 1
