Given numbers are 902,287,147,520,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,287,147,520,961 is 33129936840.
Find LCM of 902,287,147,520,961 with Prime Factorization
| 2 | 902, 287, 147, 520, 961 |
| 7 | 451, 287, 147, 260, 961 |
| 41 | 451, 41, 21, 260, 961 |
| 11, 1, 21, 260, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 11 x 1 x 21 x 260 x 961 = 33129936840
Therefore, the lowest common multiple of 902,287,147,520,961 is 33129936840.
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.
902 x 287 x 147 x 520 x 961 = 19016583746160
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
287 : 1, 7, 41, 287
147 : 1, 3, 7, 21, 49, 147
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,287,147,520,961, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
287:7x 41
147:3x 7x 7
520:2x 2x 2x 5x 13
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 41 = 574
Therefore, the value for common factors is 574.
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 = 19016583746160/(1x574)
LCM = 19016583746160/574
LCM = 33129936840
Thus, we can understand that the LCM of 902,287,147,520,961 is 33129936840.
