Given numbers are 783, 342, 612, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 342) = 29754
GCD(783, 342) = ( 783 x 342 ) / 29754
= 783 / 342
= 783
Step2:
LCM(9, 612) = 612
GCD(9, 612) = ( 9 x 612 ) / 612
= 9 / 612
= 9
Step3:
LCM(9, 427) = 3843
GCD(9, 427) = ( 9 x 427 ) / 3843
= 9 / 427
= 9
So, Greatest Common Divisor of 783, 342, 612, 427 is 1
