Given numbers are 770, 140, 257, 426
The list of prime factors of all numbers are
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 257 are 257
Prime factors of 426 are 2 x 3 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 140, 257, 426
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 140) = 1540
GCD(770, 140) = ( 770 x 140 ) / 1540
= 770 / 140
= 770
Step2:
LCM(70, 257) = 17990
GCD(70, 257) = ( 70 x 257 ) / 17990
= 70 / 257
= 70
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 770, 140, 257, 426 is 1
