Given numbers are 391,557,169,533,714
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,557,169,533,714 is 63379937166.
Find LCM of 391,557,169,533,714 with Prime Factorization
| 13 | 391, 557, 169, 533, 714 |
| 17 | 391, 557, 13, 41, 714 |
| 23, 557, 13, 41, 42 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 23 x 557 x 13 x 41 x 42 = 63379937166
Therefore, the lowest common multiple of 391,557,169,533,714 is 63379937166.
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.
391 x 557 x 169 x 533 x 714 = 14006966113686
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.
391 : 1, 17, 23, 391
557 : 1, 557
169 : 1, 13, 169
533 : 1, 13, 41, 533
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,557,169,533,714, is 1.
Now, the common factors can be found like this.
391:17x 23
557:557
169:13x 13
533:13x 41
714:2x 3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 14006966113686/(1x221)
LCM = 14006966113686/221
LCM = 63379937166
Thus, we can understand that the LCM of 391,557,169,533,714 is 63379937166.
