Given numbers are 770, 211, 420, 806
The list of prime factors of all numbers are
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 211 are 211
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 806 are 2 x 13 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 211, 420, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 211) = 162470
GCD(770, 211) = ( 770 x 211 ) / 162470
= 770 / 211
= 770
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 770, 211, 420, 806 is 1
