Find LCM of 442,267,714,298,640 with Prime Factorization
2 | 442, 267, 714, 298, 640 |
3 | 221, 267, 357, 149, 320 |
17 | 221, 89, 119, 149, 320 |
13, 89, 7, 149, 320 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 13 x 89 x 7 x 149 x 320 = 39388352640
Therefore, the lowest common multiple of 442,267,714,298,640 is 39388352640.
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.
442 x 267 x 714 x 298 x 640 = 16070447877120
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
267 : 1, 3, 89, 267
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
298 : 1, 2, 149, 298
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,267,714,298,640, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
267:3x 89
714:2x 3x 7x 17
298:2x 149
640:2x 2x 2x 2x 2x 2x 2x 5
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 16070447877120/(1x408)
LCM = 16070447877120/408
LCM = 39388352640
Thus, we can understand that the LCM of 442,267,714,298,640 is 39388352640.
