Given numbers are 145, 476, 180, 840
The list of prime factors of all numbers are
Prime factors of 145 are 5 x 29
Prime factors of 476 are 2 x 2 x 7 x 17
Prime factors of 180 are 2 x 2 x 3 x 3 x 5
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 145, 476, 180, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 476) = 69020
GCD(145, 476) = ( 145 x 476 ) / 69020
= 145 / 476
= 145
Step2:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 145, 476, 180, 840 is 1
