Given numbers are 680,357,826,938,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,357,826,938,902 is 25458426840.
Find LCM of 680,357,826,938,902 with Prime Factorization
| 2 | 680, 357, 826, 938, 902 |
| 7 | 340, 357, 413, 469, 451 |
| 17 | 340, 51, 59, 67, 451 |
| 20, 3, 59, 67, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 20 x 3 x 59 x 67 x 451 = 25458426840
Therefore, the lowest common multiple of 680,357,826,938,902 is 25458426840.
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.
680 x 357 x 826 x 938 x 902 = 169654956461760
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
357 : 1, 3, 7, 17, 21, 51, 119, 357
826 : 1, 2, 7, 14, 59, 118, 413, 826
938 : 1, 2, 7, 14, 67, 134, 469, 938
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,357,826,938,902, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
357:3x 7x 17
826:2x 7x 59
938:2x 7x 67
902:2x 11x 41
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 7x 7x 17 = 6664
Therefore, the value for common factors is 6664.
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 = 169654956461760/(1x6664)
LCM = 169654956461760/6664
LCM = 25458426840
Thus, we can understand that the LCM of 680,357,826,938,902 is 25458426840.
