Given numbers are 268, 644, 278, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(268, 644) = 43148
GCD(268, 644) = ( 268 x 644 ) / 43148
= 268 / 644
= 268
Step2:
LCM(4, 278) = 556
GCD(4, 278) = ( 4 x 278 ) / 556
= 4 / 278
= 4
Step3:
LCM(2, 789) = 1578
GCD(2, 789) = ( 2 x 789 ) / 1578
= 2 / 789
= 2
So, Greatest Common Divisor of 268, 644, 278, 789 is 1
