Given numbers are 493,645,578,695,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,645,578,695,338 is 253972711590.
Find LCM of 493,645,578,695,338 with Prime Factorization
| 2 | 493, 645, 578, 695, 338 |
| 5 | 493, 645, 289, 695, 169 |
| 17 | 493, 129, 289, 139, 169 |
| 29, 129, 17, 139, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 29 x 129 x 17 x 139 x 169 = 253972711590
Therefore, the lowest common multiple of 493,645,578,695,338 is 253972711590.
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.
493 x 645 x 578 x 695 x 338 = 43175360970300
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.
493 : 1, 17, 29, 493
645 : 1, 3, 5, 15, 43, 129, 215, 645
578 : 1, 2, 17, 34, 289, 578
695 : 1, 5, 139, 695
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,645,578,695,338, is 1.
Now, the common factors can be found like this.
493:17x 29
645:3x 5x 43
578:2x 17x 17
695:5x 139
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 43175360970300/(1x170)
LCM = 43175360970300/170
LCM = 253972711590
Thus, we can understand that the LCM of 493,645,578,695,338 is 253972711590.
