Given numbers are 435, 145, 490, 378

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 145 are 5 x 29

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 435, 145, 490, 378

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(435, 145) = 435

GCD(435, 145) = ( 435 x 145 ) / 435

= 435 / 145

= 435

Step2:

LCM(145, 490) = 14210

GCD(145, 490) = ( 145 x 490 ) / 14210

= 145 / 490

= 145

Step3:

LCM(5, 378) = 1890

GCD(5, 378) = ( 5 x 378 ) / 1890

= 5 / 378

= 5

So, Greatest Common Divisor of 435, 145, 490, 378 is 1
