The LCM of two numbers is twice their HCF?
5 and 10 lcm- 10 and hcf= 5
What is the LCM and the HCF of 18 and 70?
18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
What is the hcf and lcm of 5 and 15?
hcf(5, 15) = 5 lcm(5, 15) = 15.
What is the LCM of two that have no common factors greater than 1?
If there is no common factor greater than 1, then the lcm of those numbers is the product of those numbers. eg hcf(5, 7) = 1 → lcm(5, 7) = 5 x 7 = 35 eg hcf(4, 9) = 1 → lcm(4, 9) = 4 x 9 = 36
What is the HCF and LCM of 405 and 140?
2 x 2 x 5 x 7 = 140 5 x 9 x 9 = 405 HCF is 5 LCM is 11,340
What is the hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
What is the HCF and the LCM of 57?
You need at least two numbers to find both of those. If that's 5 and 7, the GCF is 1, the LCM is 35.
Is the LCM of 50 120 and 225 is 5?
No, that is the HCF. The LCM is 1800
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
What two numbers have a LCM of 60 and a HCF of 5?
5 and 60 do.
What is the HCF of 210 and 165?
The HCF of 165 and 210 is 15. The LCM is 2310.
What is the LCM of 10and20 to their hcf?
LCM is 20 and the hcf is 10
What number have an LCM of 75 and HCF of 5?
15 and 25
Which two numbers have an LCM of 60 and HCF of 5?
4
What is the hcf and the LCM of 10 and 15?
5 and 30, respectively.
What is the HCF and the LCM of 616 and 728?
HCF = 56 LCM = 8008 616 = 2^3 x 7 x 11 728 = 2^3 x 7 x 13 hcf = 2^3 x 7 = 56 lcm = 2^3 x 7 x 11 x 13 = 8008
What is the HCF and LCM of 270 and 195?
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
What is the HCF and LCM of 3 and 18?
HCF = 3... LCM = 18 !
What is the HCF and LCM of 42 and 84?
hcf = 42, lcm = 84.
What is the HCF and the LCM of 144 and 192?
HCF is 48 and LCM is 576
What Is The Hcf And Lcm 120 And 180?
HCF is 60 and the LCM is 360
What is the LCM and hcf of 40 and 24?
They are: LCM = 120 and hcf = 8
What is the least common multiple of 65 and 155?
LCM of two numbers = product/HCF; 65 = 5 x 13, 155 = 5 x 31 so HCF is 5 and LCM is 65 x 155/5 = 2015
What is the LCM of 462 and 630?
LCM of two numbers is their product divided by their HCF. First find HCF: 462 = 2 x 3 x 7 x 11; 630 = 2 x 3 x 3 x 5 x 7. The common factors are 2 x 3 x 7 ie HCF = 42 LCM is therefore 462 x 630 / 42 ie 11 x 630 = 6930
What is the HCF and LCM of 200 and 175?
200 = 23 x 52 175 = 52 x 7 hcf = 52 = 25 lcm = 23 x 52 x 7 = 1400
