Given numbers are 649, 100, 698, 771

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 698 are 2 x 349

Prime factors of 771 are 3 x 257

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

Given numbers are 649, 100, 698, 771

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

Apply this formula for all numbers.

Step1:

LCM(649, 100) = 64900

GCD(649, 100) = ( 649 x 100 ) / 64900

= 649 / 100

= 649

Step2:

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

= 1 / 698

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 649, 100, 698, 771 is 1
