Given numbers are 609,980,974,207,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,980,974,207,397 is 1137401736660.
Find LCM of 609,980,974,207,397 with Prime Factorization
| 2 | 609, 980, 974, 207, 397 |
| 3 | 609, 490, 487, 207, 397 |
| 7 | 203, 490, 487, 69, 397 |
| 29, 70, 487, 69, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 70 x 487 x 69 x 397 = 1137401736660
Therefore, the lowest common multiple of 609,980,974,207,397 is 1137401736660.
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.
609 x 980 x 974 x 207 x 397 = 47770872939720
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
974 : 1, 2, 487, 974
207 : 1, 3, 9, 23, 69, 207
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,980,974,207,397, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
980:2x 2x 5x 7x 7
974:2x 487
207:3x 3x 23
397:397
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 = 47770872939720/(1x42)
LCM = 47770872939720/42
LCM = 1137401736660
Thus, we can understand that the LCM of 609,980,974,207,397 is 1137401736660.
