Given numbers are 352,607,749,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 352,607,749,642 is 480103008.
Find LCM of 352,607,749,642 with Prime Factorization
| 2 | 352, 607, 749, 642 |
| 107 | 176, 607, 749, 321 |
| 176, 607, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 176 x 607 x 7 x 3 = 480103008
Therefore, the lowest common multiple of 352,607,749,642 is 480103008.
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.
352 x 607 x 749 x 642 = 102742043712
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.
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
607 : 1, 607
749 : 1, 7, 107, 749
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 352,607,749,642, is 1.
Now, the common factors can be found like this.
352:2x 2x 2x 2x 2x 11
607:607
749:7x 107
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 107 = 214
Therefore, the value for common factors is 214.
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 = 102742043712/(1x214)
LCM = 102742043712/214
LCM = 480103008
Thus, we can understand that the LCM of 352,607,749,642 is 480103008.
