18 x 10 = 180 60 x 3 = 180 The lowest common multiple of the two numbers is 180.

15 and 4 and 60 and 2 20 and 3, etc

the lcm for 60 and 72 is 360.

Least Common Multiple (LCM) for 3 60 is 60.

The LCM is: 300

Since the product of two numbers is equal to the product of their GCF and LCM, the GCF of two numbers is equal to their product divided by their LCM and their LCM is equal to their product divided by their GCF.

HCF is 60 and the LCM is 360

30 and 60 have an LCM of 60.

HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.

Factorize the LCM 20 = 2 x 2 x 5 Factorize the HCF 300 = 2 x 2x3x5x5 The HCF is the common factor for both numbers whereas the LCM contains all the unique factors of both numbers. So, 2 x 2x5 or 20 is a common factor for both numbers. The factors remaining are 3 and 5. So, 3 is a factor of one number and 5 is the factor of the second number. The first number = 20x 3 = 60 The second number = 20x 5 = 100 So 60 and 100 are two numbers Answer = 60 and 100

To do this you first need to express each number as a product of their prime factors: 36 = 2x2x3x3 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have a 2 a 2 and a 3 as prime factors. Multiply these together and you get 12. Therefore the HCF of 36 and 60 is 12. To find the LCM, multiply the numbers together and divide by the hcf: 36x60/12 = 180 So 180 is the LCM of 36 and 60.

To find the LCM you first have to break the numbers into their prime factors: 60 = 2x2x3x5 100 = 2x2x5x5 The next step is to identify the HCF. In this case it's 2x2x5 = 20. Finally, you multiply the numbers together and divide by the HCF: 60x100/20 = 300 Therefore the LCM of 60 and 100 is 300.

GCF is 60, LCM is 900

Any two numbers that have a common factor greater than 1 will have a LCM less than their product, eg: LCM(10, 15) = 30 < 10 x 15 = 150 (since HCF(10, 15) = 5) LCM(6, 10) = 30 < 6 x 10 = 60 (since HCF(6, 10) = 2) LCM(18, 27) = 54 < 18 x 27 = 486 (since HCF(18, 27) = 9)

6 and 60, respectively.

You need at least two numbers to find a GCF.
