GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 678) = 88818
GCD(786, 678) = ( 786 x 678 ) / 88818
= 786 / 678
= 786
Step2:
LCM(6, 516) = 516
GCD(6, 516) = ( 6 x 516 ) / 516
= 6 / 516
= 6
Step3:
LCM(6, 392) = 1176
GCD(6, 392) = ( 6 x 392 ) / 1176
= 6 / 392
= 6
So, Greatest Common Divisor of 786, 678, 516, 392 is 2
