Given numbers are 662,526,974,240,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,526,974,240,644 is 1638135497040.
Find LCM of 662,526,974,240,644 with Prime Factorization
| 2 | 662, 526, 974, 240, 644 |
| 2 | 331, 263, 487, 120, 322 |
| 331, 263, 487, 60, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 331 x 263 x 487 x 60 x 161 = 1638135497040
Therefore, the lowest common multiple of 662,526,974,240,644 is 1638135497040.
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.
662 x 526 x 974 x 240 x 644 = 52420335905280
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.
662 : 1, 2, 331, 662
526 : 1, 2, 263, 526
974 : 1, 2, 487, 974
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,526,974,240,644, is 2.
Now, the common factors can be found like this.
662:2x 331
526:2x 263
974:2x 487
240:2x 2x 2x 2x 3x 5
644:2x 2x 7x 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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 52420335905280/(2x16)
LCM = 52420335905280/32
LCM = 1638135497040
Thus, we can understand that the LCM of 662,526,974,240,644 is 1638135497040.
