GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 480) = 62880
GCD(786, 480) = ( 786 x 480 ) / 62880
= 786 / 480
= 786
Step2:
LCM(6, 660) = 660
GCD(6, 660) = ( 6 x 660 ) / 660
= 6 / 660
= 6
Step3:
LCM(6, 813) = 1626
GCD(6, 813) = ( 6 x 813 ) / 1626
= 6 / 813
= 6
So, Greatest Common Divisor of 786, 480, 660, 813 is 3
