Given numbers are 386, 620, 551, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 620) = 119660
GCD(386, 620) = ( 386 x 620 ) / 119660
= 386 / 620
= 386
Step2:
LCM(2, 551) = 1102
GCD(2, 551) = ( 2 x 551 ) / 1102
= 2 / 551
= 2
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 386, 620, 551, 668 is 1
