Given numbers are 790,462,838,391,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,462,838,391,437 is 568045929990.
Find LCM of 790,462,838,391,437 with Prime Factorization
| 2 | 790, 462, 838, 391, 437 |
| 23 | 395, 231, 419, 391, 437 |
| 395, 231, 419, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 395 x 231 x 419 x 17 x 19 = 568045929990
Therefore, the lowest common multiple of 790,462,838,391,437 is 568045929990.
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.
790 x 462 x 838 x 391 x 437 = 52260225559080
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
838 : 1, 2, 419, 838
391 : 1, 17, 23, 391
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,462,838,391,437, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
462:2x 3x 7x 11
838:2x 419
391:17x 23
437:19x 23
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 23 = 92
Therefore, the value for common factors is 92.
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 = 52260225559080/(1x92)
LCM = 52260225559080/92
LCM = 568045929990
Thus, we can understand that the LCM of 790,462,838,391,437 is 568045929990.
