Given numbers are 573,728,641,918,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 573,728,641,918,403 is 1268227468872.
Find LCM of 573,728,641,918,403 with Prime Factorization
| 2 | 573, 728, 641, 918, 403 |
| 3 | 573, 364, 641, 459, 403 |
| 13 | 191, 364, 641, 153, 403 |
| 191, 28, 641, 153, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 191 x 28 x 641 x 153 x 31 = 1268227468872
Therefore, the lowest common multiple of 573,728,641,918,403 is 1268227468872.
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.
573 x 728 x 641 x 918 x 403 = 98921742572016
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.
573 : 1, 3, 191, 573
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
641 : 1, 641
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 573,728,641,918,403, is 1.
Now, the common factors can be found like this.
573:3x 191
728:2x 2x 2x 7x 13
641:641
918:2x 3x 3x 3x 17
403:13x 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 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 98921742572016/(1x78)
LCM = 98921742572016/78
LCM = 1268227468872
Thus, we can understand that the LCM of 573,728,641,918,403 is 1268227468872.
