Given numbers are 671,470,282,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,470,282,220 is 1892220.
Find LCM of 671,470,282,220 with Prime Factorization
| 2 | 671, 470, 282, 220 |
| 5 | 671, 235, 141, 110 |
| 11 | 671, 47, 141, 22 |
| 47 | 61, 47, 141, 2 |
| 61, 1, 3, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 47 x 61 x 1 x 3 x 2 = 1892220
Therefore, the lowest common multiple of 671,470,282,220 is 1892220.
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.
671 x 470 x 282 x 220 = 19565554800
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.
671 : 1, 11, 61, 671
470 : 1, 2, 5, 10, 47, 94, 235, 470
282 : 1, 2, 3, 6, 47, 94, 141, 282
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,470,282,220, is 1.
Now, the common factors can be found like this.
671:11x 61
470:2x 5x 47
282:2x 3x 47
220:2x 2x 5x 11
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 11x 47 = 10340
Therefore, the value for common factors is 10340.
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 = 19565554800/(1x10340)
LCM = 19565554800/10340
LCM = 1892220
Thus, we can understand that the LCM of 671,470,282,220 is 1892220.
