Given numbers are 749,619,429,378,514
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,619,429,378,514 is 920100755574.
Find LCM of 749,619,429,378,514 with Prime Factorization
| 2 | 749, 619, 429, 378, 514 |
| 3 | 749, 619, 429, 189, 257 |
| 7 | 749, 619, 143, 63, 257 |
| 107, 619, 143, 9, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 107 x 619 x 143 x 9 x 257 = 920100755574
Therefore, the lowest common multiple of 749,619,429,378,514 is 920100755574.
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.
749 x 619 x 429 x 378 x 514 = 38644231734108
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.
749 : 1, 7, 107, 749
619 : 1, 619
429 : 1, 3, 11, 13, 33, 39, 143, 429
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
514 : 1, 2, 257, 514
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,619,429,378,514, is 1.
Now, the common factors can be found like this.
749:7x 107
619:619
429:3x 11x 13
378:2x 3x 3x 3x 7
514:2x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 38644231734108/(1x42)
LCM = 38644231734108/42
LCM = 920100755574
Thus, we can understand that the LCM of 749,619,429,378,514 is 920100755574.
