Given numbers are 629,668,356,490,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,668,356,490,642 is 2940953997660.
Find LCM of 629,668,356,490,642 with Prime Factorization
2 | 629, 668, 356, 490, 642 |
2 | 629, 334, 178, 245, 321 |
629, 167, 89, 245, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 629 x 167 x 89 x 245 x 321 = 2940953997660
Therefore, the lowest common multiple of 629,668,356,490,642 is 2940953997660.
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 668 x 356 x 490 x 642 = 47055263962560
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
668 : 1, 2, 4, 167, 334, 668
356 : 1, 2, 4, 89, 178, 356
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,668,356,490,642, is 1.
Now, the common factors can be found like this.
629:17x 37
668:2x 2x 167
356:2x 2x 89
490:2x 5x 7x 7
642:2x 3x 107
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 2 = 16
Therefore, the value for common factors is 16.
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 = 47055263962560/(1x16)
LCM = 47055263962560/16
LCM = 2940953997660
Thus, we can understand that the LCM of 629,668,356,490,642 is 2940953997660.
