Given numbers are 770, 898, 603, 780

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 898 are 2 x 449

Prime factors of 603 are 3 x 3 x 67

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 770, 898, 603, 780

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

Apply this formula for all numbers.

Step1:

LCM(770, 898) = 345730

GCD(770, 898) = ( 770 x 898 ) / 345730

= 770 / 898

= 770

Step2:

LCM(2, 603) = 1206

GCD(2, 603) = ( 2 x 603 ) / 1206

= 2 / 603

= 2

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 770, 898, 603, 780 is 1
