Given numbers are 754,490,929,640,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,490,929,640,791 is 1241113677440.
Find LCM of 754,490,929,640,791 with Prime Factorization
| 2 | 754, 490, 929, 640, 791 |
| 5 | 377, 245, 929, 320, 791 |
| 7 | 377, 49, 929, 64, 791 |
| 377, 7, 929, 64, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 377 x 7 x 929 x 64 x 113 = 1241113677440
Therefore, the lowest common multiple of 754,490,929,640,791 is 1241113677440.
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.
754 x 490 x 929 x 640 x 791 = 173755914841600
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
929 : 1, 929
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,490,929,640,791, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
490:2x 5x 7x 7
929:929
640:2x 2x 2x 2x 2x 2x 2x 5
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 173755914841600/(1x140)
LCM = 173755914841600/140
LCM = 1241113677440
Thus, we can understand that the LCM of 754,490,929,640,791 is 1241113677440.
