# The GCF of two numbers is 5 the LCM is 90 the two numbers add up to 55 what are the two numbers?

10 and 45. 10=5*2 10+45=55 45*2=90 45=5*9 10*9=90

### How Given any two numbers which is greater the LCM of the numbers or. The GCF of the numbers why?

The LCM will never be less than the GCF. To be a multiple of both numbers, the LCM will have to be equal to or greater than the larger number. To be a factor of both numbers, the GCF will have to be equal to or less than the smaller number. The only problem comes when you're comparing a number to itself. The LCM of 10 and 10 is 10. The GCF of 10 and…
