Given numbers are 721,663,650,712,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,663,650,712,897 is 195702616200.
Find LCM of 721,663,650,712,897 with Prime Factorization
| 2 | 721, 663, 650, 712, 897 |
| 3 | 721, 663, 325, 356, 897 |
| 13 | 721, 221, 325, 356, 299 |
| 721, 17, 25, 356, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 721 x 17 x 25 x 356 x 23 = 195702616200
Therefore, the lowest common multiple of 721,663,650,712,897 is 195702616200.
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 663 x 650 x 712 x 897 = 198442452826800
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
663 : 1, 3, 13, 17, 39, 51, 221, 663
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
712 : 1, 2, 4, 8, 89, 178, 356, 712
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,663,650,712,897, is 1.
Now, the common factors can be found like this.
721:7x 103
663:3x 13x 17
650:2x 5x 5x 13
712:2x 2x 2x 89
897:3x 13x 23
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 13x 13 = 1014
Therefore, the value for common factors is 1014.
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 = 198442452826800/(1x1014)
LCM = 198442452826800/1014
LCM = 195702616200
Thus, we can understand that the LCM of 721,663,650,712,897 is 195702616200.
