Given numbers are 720, 475, 490, 606
The list of prime factors of all numbers are
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 475 are 5 x 5 x 19
Prime factors of 490 are 2 x 5 x 7 x 7
Prime factors of 606 are 2 x 3 x 101
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 475, 490, 606
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 475) = 68400
GCD(720, 475) = ( 720 x 475 ) / 68400
= 720 / 475
= 720
Step2:
LCM(5, 490) = 490
GCD(5, 490) = ( 5 x 490 ) / 490
= 5 / 490
= 5
Step3:
LCM(5, 606) = 3030
GCD(5, 606) = ( 5 x 606 ) / 3030
= 5 / 606
= 5
So, Greatest Common Divisor of 720, 475, 490, 606 is 1
