Given numbers are 434,630,971,217,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,630,971,217,287 is 777508830.
Find LCM of 434,630,971,217,287 with Prime Factorization
| 2 | 434, 630, 971, 217, 287 |
| 7 | 217, 315, 971, 217, 287 |
| 31 | 31, 45, 971, 31, 41 |
| 1, 45, 971, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 1 x 45 x 971 x 1 x 41 = 777508830
Therefore, the lowest common multiple of 434,630,971,217,287 is 777508830.
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.
434 x 630 x 971 x 217 x 287 = 16534502778780
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
971 : 1, 971
217 : 1, 7, 31, 217
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,630,971,217,287, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
630:2x 3x 3x 5x 7
971:971
217:7x 31
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 7x 31 = 21266
Therefore, the value for common factors is 21266.
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 = 16534502778780/(1x21266)
LCM = 16534502778780/21266
LCM = 777508830
Thus, we can understand that the LCM of 434,630,971,217,287 is 777508830.
