Given numbers are 721,544,533,574
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,544,533,574 is 209055392.
Find LCM of 721,544,533,574 with Prime Factorization
| 2 | 721, 544, 533, 574 |
| 7 | 721, 272, 533, 287 |
| 41 | 103, 272, 533, 41 |
| 103, 272, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 103 x 272 x 13 x 1 = 209055392
Therefore, the lowest common multiple of 721,544,533,574 is 209055392.
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.
721 x 544 x 533 x 574 = 119997795008
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.
721 : 1, 7, 103, 721
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
533 : 1, 13, 41, 533
574 : 1, 2, 7, 14, 41, 82, 287, 574
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,544,533,574, is 1.
Now, the common factors can be found like this.
721:7x 103
544:2x 2x 2x 2x 2x 17
533:13x 41
574:2x 7x 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 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 = 119997795008/(1x574)
LCM = 119997795008/574
LCM = 209055392
Thus, we can understand that the LCM of 721,544,533,574 is 209055392.
