Given numbers are 138, 324, 370, 147
The list of prime factors of all numbers are
Prime factors of 138 are 2 x 3 x 23
Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 370 are 2 x 5 x 37
Prime factors of 147 are 3 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 138, 324, 370, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 324) = 7452
GCD(138, 324) = ( 138 x 324 ) / 7452
= 138 / 324
= 138
Step2:
LCM(6, 370) = 1110
GCD(6, 370) = ( 6 x 370 ) / 1110
= 6 / 370
= 6
Step3:
LCM(2, 147) = 294
GCD(2, 147) = ( 2 x 147 ) / 294
= 2 / 147
= 2
So, Greatest Common Divisor of 138, 324, 370, 147 is 1
