Oh honey, the Highest Common Factor (HCF) of 5 and 7 is 1 because those two numbers don't have any common factors other than 1. The Lowest Common Multiple (LCM) of 5 and 7 is simply the product of the two numbers, which is 35. So there you have it, simple math for a simple question!
hcf(5, 15) = 5 lcm(5, 15) = 15.
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
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
5 and 30, respectively.
4
hcf(5, 15) = 5 lcm(5, 15) = 15.
2 x 2 x 5 x 7 = 140 5 x 9 x 9 = 405 HCF is 5 LCM is 11,340
5 and 10 lcm- 10 and hcf= 5
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
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
No, that is the HCF. The LCM is 1800
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.
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
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 .
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
200 = 23 x 52 175 = 52 x 7 hcf = 52 = 25 lcm = 23 x 52 x 7 = 1400
LCM is 20 and the hcf is 10
