The LCM of 370,874,699,646,391 is 1921362270.
Find LCM of 370,874,699,646,391 with Prime Factorization
| 2 | 370, 874, 699, 646, 391 |
| 17 | 185, 437, 699, 323, 391 |
| 19 | 185, 437, 699, 19, 23 |
| 23 | 185, 23, 699, 1, 23 |
| 185, 1, 699, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 23 x 185 x 1 x 699 x 1 x 1 = 1921362270
Therefore, the lowest common multiple of 370,874,699,646,391 is 1921362270.
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.
370 x 874 x 699 x 646 x 391 = 57095201215320
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.
370 : 1, 2, 5, 10, 37, 74, 185, 370
874 : 1, 2, 19, 23, 38, 46, 437, 874
699 : 1, 3, 233, 699
646 : 1, 2, 17, 19, 34, 38, 323, 646
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 370,874,699,646,391, is 1.
Now, the common factors can be found like this.
370:2x 5x 37
874:2x 19x 23
699:3x 233
646:2x 17x 19
391:17x 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 17x 19x 23 = 29716
Therefore, the value for common factors is 29716.
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 = 57095201215320/(1x29716)
LCM = 57095201215320/29716
LCM = 1921362270
Thus, we can understand that the LCM of 370,874,699,646,391 is 1921362270.
