Given numbers are 462, 686, 787, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 686) = 22638
GCD(462, 686) = ( 462 x 686 ) / 22638
= 462 / 686
= 462
Step2:
LCM(14, 787) = 11018
GCD(14, 787) = ( 14 x 787 ) / 11018
= 14 / 787
= 14
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 462, 686, 787, 153 is 1
