Given numbers are 753, 378, 836, 215

The list of prime factors of all numbers are

Prime factors of 753 are 3 x 251

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

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 215 are 5 x 43

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

Given numbers are 753, 378, 836, 215

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

Apply this formula for all numbers.

Step1:

LCM(753, 378) = 94878

GCD(753, 378) = ( 753 x 378 ) / 94878

= 753 / 378

= 753

Step2:

LCM(3, 836) = 2508

GCD(3, 836) = ( 3 x 836 ) / 2508

= 3 / 836

= 3

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 753, 378, 836, 215 is 1
