Find LCM of 397,754,299,618,639 with Prime Factorization
| 2 | 397, 754, 299, 618, 639 |
| 3 | 397, 377, 299, 309, 639 |
| 13 | 397, 377, 299, 103, 213 |
| 397, 29, 23, 103, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 397 x 29 x 23 x 103 x 213 = 453135170358
Therefore, the lowest common multiple of 397,754,299,618,639 is 453135170358.
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.
397 x 754 x 299 x 618 x 639 = 35344543287924
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.
397 : 1, 397
754 : 1, 2, 13, 26, 29, 58, 377, 754
299 : 1, 13, 23, 299
618 : 1, 2, 3, 6, 103, 206, 309, 618
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,754,299,618,639, is 1.
Now, the common factors can be found like this.
397:397
754:2x 13x 29
299:13x 23
618:2x 3x 103
639:3x 3x 71
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 13 = 78
Therefore, the value for common factors is 78.
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 = 35344543287924/(1x78)
LCM = 35344543287924/78
LCM = 453135170358
Thus, we can understand that the LCM of 397,754,299,618,639 is 453135170358.
