Given numbers are 411, 761, 780, 551

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

Prime factors of 761 are 761

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

Prime factors of 551 are 19 x 29

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

Given numbers are 411, 761, 780, 551

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

Apply this formula for all numbers.

Step1:

LCM(411, 761) = 312771

GCD(411, 761) = ( 411 x 761 ) / 312771

= 411 / 761

= 411

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 411, 761, 780, 551 is 1
