GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 978) = 75306
GCD(462, 978) = ( 462 x 978 ) / 75306
= 462 / 978
= 462
Step2:
LCM(6, 652) = 1956
GCD(6, 652) = ( 6 x 652 ) / 1956
= 6 / 652
= 6
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 462, 978, 652, 645 is 1
