Given numbers are 473,128,220,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,128,220,430 is 302720.
Find LCM of 473,128,220,430 with Prime Factorization
| 2 | 473, 128, 220, 430 |
| 2 | 473, 64, 110, 215 |
| 5 | 473, 32, 55, 215 |
| 11 | 473, 32, 11, 43 |
| 43 | 43, 32, 1, 43 |
| 1, 32, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 43 x 1 x 32 x 1 x 1 = 302720
Therefore, the lowest common multiple of 473,128,220,430 is 302720.
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.
473 x 128 x 220 x 430 = 5727462400
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.
473 : 1, 11, 43, 473
128 : 1, 2, 4, 8, 16, 32, 64, 128
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,128,220,430, is 1.
Now, the common factors can be found like this.
473:11x 43
128:2x 2x 2x 2x 2x 2x 2
220:2x 2x 5x 11
430:2x 5x 43
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 2x 5x 11x 43 = 18920
Therefore, the value for common factors is 18920.
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 = 5727462400/(1x18920)
LCM = 5727462400/18920
LCM = 302720
Thus, we can understand that the LCM of 473,128,220,430 is 302720.
