Prime factors of 294 are 2 x 3 x 7 x 7
Prime factors of 678 are 2 x 3 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 550, 455, 294, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 455) = 50050
GCD(550, 455) = ( 550 x 455 ) / 50050
= 550 / 455
= 550
Step2:
LCM(5, 294) = 1470
GCD(5, 294) = ( 5 x 294 ) / 1470
= 5 / 294
= 5
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 550, 455, 294, 678 is 1
