Given numbers are 775, 390, 882, 840

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

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 775, 390, 882, 840

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

Apply this formula for all numbers.

Step1:

LCM(775, 390) = 60450

GCD(775, 390) = ( 775 x 390 ) / 60450

= 775 / 390

= 775

Step2:

LCM(5, 882) = 4410

GCD(5, 882) = ( 5 x 882 ) / 4410

= 5 / 882

= 5

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 775, 390, 882, 840 is 1
