Given numbers are 280, 270, 225, 122
The list of prime factors of all numbers are
Prime factors of 280 are 2 x 2 x 2 x 5 x 7
Prime factors of 270 are 2 x 3 x 3 x 3 x 5
Prime factors of 225 are 3 x 3 x 5 x 5
Prime factors of 122 are 2 x 61
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 280, 270, 225, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 270) = 7560
GCD(280, 270) = ( 280 x 270 ) / 7560
= 280 / 270
= 280
Step2:
LCM(10, 225) = 450
GCD(10, 225) = ( 10 x 225 ) / 450
= 10 / 225
= 10
Step3:
LCM(5, 122) = 610
GCD(5, 122) = ( 5 x 122 ) / 610
= 5 / 122
= 5
So, Greatest Common Divisor of 280, 270, 225, 122 is 1
