Given numbers are 572,640,460,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 572,640,460,670 is 141032320.
Find LCM of 572,640,460,670 with Prime Factorization
| 2 | 572, 640, 460, 670 |
| 2 | 286, 320, 230, 335 |
| 5 | 143, 160, 115, 335 |
| 143, 32, 23, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 143 x 32 x 23 x 67 = 141032320
Therefore, the lowest common multiple of 572,640,460,670 is 141032320.
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.
572 x 640 x 460 x 670 = 112825856000
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
670 : 1, 2, 5, 10, 67, 134, 335, 670
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,640,460,670, is 2.
Now, the common factors can be found like this.
572:2x 2x 11x 13
640:2x 2x 2x 2x 2x 2x 2x 5
460:2x 2x 5x 23
670:2x 5x 67
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 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 112825856000/(2x400)
LCM = 112825856000/800
LCM = 141032320
Thus, we can understand that the LCM of 572,640,460,670 is 141032320.
