Given numbers are 507,253,221,951
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,253,221,951 is 691252419.
Find LCM of 507,253,221,951 with Prime Factorization
| 3 | 507, 253, 221, 951 |
| 13 | 169, 253, 221, 317 |
| 13, 253, 17, 317 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 13 x 253 x 17 x 317 = 691252419
Therefore, the lowest common multiple of 507,253,221,951 is 691252419.
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.
507 x 253 x 221 x 951 = 26958844341
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.
507 : 1, 3, 13, 39, 169, 507
253 : 1, 11, 23, 253
221 : 1, 13, 17, 221
951 : 1, 3, 317, 951
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,253,221,951, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
253:11x 23
221:13x 17
951:3x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 26958844341/(1x39)
LCM = 26958844341/39
LCM = 691252419
Thus, we can understand that the LCM of 507,253,221,951 is 691252419.
