Given numbers are 629,961,438,641,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,961,438,641,870 is 24607878587790.
Find LCM of 629,961,438,641,870 with Prime Factorization
| 2 | 629, 961, 438, 641, 870 |
| 3 | 629, 961, 219, 641, 435 |
| 629, 961, 73, 641, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 629 x 961 x 73 x 641 x 145 = 24607878587790
Therefore, the lowest common multiple of 629,961,438,641,870 is 24607878587790.
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.
629 x 961 x 438 x 641 x 870 = 147647271526740
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.
629 : 1, 17, 37, 629
961 : 1, 31, 961
438 : 1, 2, 3, 6, 73, 146, 219, 438
641 : 1, 641
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,961,438,641,870, is 1.
Now, the common factors can be found like this.
629:17x 37
961:31x 31
438:2x 3x 73
641:641
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 147647271526740/(1x6)
LCM = 147647271526740/6
LCM = 24607878587790
Thus, we can understand that the LCM of 629,961,438,641,870 is 24607878587790.
