Divide the product of the original numbers by 108, the LCM. The result will be the GCF.

To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.

LCM is 20 and the hcf is 10

HCF = 3... LCM = 18 !

hcf = 42, lcm = 84.

HCF is 48 and LCM is 576

HCF is 60 and the LCM is 360

hcf is 1 and LCM is 35

They are: LCM = 120 and hcf = 8

To find the LCM of two numbers, you first need to find the HCF. In this case, the HCF is clearly x. Next you multiply the numbers together and divide by the HCF. x(6x)/x = 6x. Therefore the LCM of x and 6x is 6x.

The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.

LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.

To consecutive numbers cannot have any common prime factors. Thus the HCF of p and (p+1) will be 1. To find the LCM, you multiply two numbers together and divide by the HCF. In this case, you'd do p(p+1)/1 This simplifies to p2+p So the HCF is 1 and the LCM is p2+p

No because 16 will not divide into 240 with no remainder.

The HCF = 20 The LCM = 600

GCF is 60, LCM is 900

5 and 10 lcm- 10 and hcf= 5

hcf: 1 lcm: 112,038

To find the LCM of two numbers, you multiply them together and divide by the HCF. In this case one of the numbers is 1 and so the HCF can only be 1. Thus all we have to do is multiply the numbers together: 1x3 = 3 And therefore the LCM of 1 and 3 is 3.

To find the LCM of two numbers you need to multiply them together and then divide by the HCF. In this case, the numbers are coprime and so the HCF will be 1. Therefore was just have to multiply the numbers together: 7x3 = 21 And so the LCM of 7 and 3 is 21.

The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.

LCM = Product/HCF = 384

124

To find the LCM of two numbers, you first split them into their prime factors: 30 = 2x3x5 75 = 3x5x5 Next you need to work out the HCF. Here, the HCF will be 3x5 = 15. Finally, you multiply the numbers together and divide by the HCF. 30x75/15 = 150. Therefore the LCM of 30 and 75 is 150.

Yes: product of a & b = LCM x HCF so b = (LCM x HCF)/a
