Given numbers are 301,438,518,220,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 301,438,518,220,455 is 6975548580.
Find LCM of 301,438,518,220,455 with Prime Factorization
| 2 | 301, 438, 518, 220, 455 |
| 5 | 301, 219, 259, 110, 455 |
| 7 | 301, 219, 259, 22, 91 |
| 43, 219, 37, 22, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 43 x 219 x 37 x 22 x 13 = 6975548580
Therefore, the lowest common multiple of 301,438,518,220,455 is 6975548580.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
301 x 438 x 518 x 220 x 455 = 6836037608400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
301 : 1, 7, 43, 301
438 : 1, 2, 3, 6, 73, 146, 219, 438
518 : 1, 2, 7, 14, 37, 74, 259, 518
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 301,438,518,220,455, is 1.
Now, the common factors can be found like this.
301:7x 43
438:2x 3x 73
518:2x 7x 37
220:2x 2x 5x 11
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7x 7 = 980
Therefore, the value for common factors is 980.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 6836037608400/(1x980)
LCM = 6836037608400/980
LCM = 6975548580
Thus, we can understand that the LCM of 301,438,518,220,455 is 6975548580.
