Find LCM of 970,291,698,561,957 with Prime Factorization
| 2 | 970, 291, 698, 561, 957 |
| 3 | 485, 291, 349, 561, 957 |
| 11 | 485, 97, 349, 187, 319 |
| 97 | 485, 97, 349, 17, 29 |
| 5, 1, 349, 17, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 97 x 5 x 1 x 349 x 17 x 29 = 5507544570
Therefore, the lowest common multiple of 970,291,698,561,957 is 5507544570.
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.
970 x 291 x 698 x 561 x 957 = 105777901011420
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
291 : 1, 3, 97, 291
698 : 1, 2, 349, 698
561 : 1, 3, 11, 17, 33, 51, 187, 561
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,291,698,561,957, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
291:3x 97
698:2x 349
561:3x 11x 17
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 97 = 19206
Therefore, the value for common factors is 19206.
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 = 105777901011420/(1x19206)
LCM = 105777901011420/19206
LCM = 5507544570
Thus, we can understand that the LCM of 970,291,698,561,957 is 5507544570.
