Given numbers are 709,525,652,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,525,652,840 is 485381400.
Find LCM of 709,525,652,840 with Prime Factorization
| 2 | 709, 525, 652, 840 |
| 2 | 709, 525, 326, 420 |
| 3 | 709, 525, 163, 210 |
| 5 | 709, 175, 163, 70 |
| 7 | 709, 35, 163, 14 |
| 709, 5, 163, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 709 x 5 x 163 x 2 = 485381400
Therefore, the lowest common multiple of 709,525,652,840 is 485381400.
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.
709 x 525 x 652 x 840 = 203860188000
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.
709 : 1, 709
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
652 : 1, 2, 4, 163, 326, 652
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 709,525,652,840, is 1.
Now, the common factors can be found like this.
709:709
525:3x 5x 5x 7
652:2x 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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 203860188000/(1x420)
LCM = 203860188000/420
LCM = 485381400
Thus, we can understand that the LCM of 709,525,652,840 is 485381400.
