Given numbers are 520, 145, 712, 666
The list of prime factors of all numbers are
Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 145 are 5 x 29
Prime factors of 712 are 2 x 2 x 2 x 89
Prime factors of 666 are 2 x 3 x 3 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 520, 145, 712, 666
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 145) = 15080
GCD(520, 145) = ( 520 x 145 ) / 15080
= 520 / 145
= 520
Step2:
LCM(5, 712) = 3560
GCD(5, 712) = ( 5 x 712 ) / 3560
= 5 / 712
= 5
Step3:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
So, Greatest Common Divisor of 520, 145, 712, 666 is 1
