The list of prime factors of all numbers are
Prime factors of 138 are 2 x 3 x 23
Prime factors of 514 are 2 x 257
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 785 are 5 x 157
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 138, 514, 648, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 514) = 35466
GCD(138, 514) = ( 138 x 514 ) / 35466
= 138 / 514
= 138
Step2:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
Step3:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
So, Greatest Common Divisor of 138, 514, 648, 785 is 1
