Given numbers are 604,671,326,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 604,671,326,840 is 13872871320.
Find LCM of 604,671,326,840 with Prime Factorization
| 2 | 604, 671, 326, 840 |
| 2 | 302, 671, 163, 420 |
| 151, 671, 163, 210 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 151 x 671 x 163 x 210 = 13872871320
Therefore, the lowest common multiple of 604,671,326,840 is 13872871320.
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.
604 x 671 x 326 x 840 = 110982970560
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.
604 : 1, 2, 4, 151, 302, 604
671 : 1, 11, 61, 671
326 : 1, 2, 163, 326
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,671,326,840, is 1.
Now, the common factors can be found like this.
604:2x 2x 151
671:11x 61
326:2x 163
840:2x 2x 2x 3x 5x 7
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 2 = 8
Therefore, the value for common factors is 8.
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 = 110982970560/(1x8)
LCM = 110982970560/8
LCM = 13872871320
Thus, we can understand that the LCM of 604,671,326,840 is 13872871320.
