Given numbers are 929,490,992,819,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 929,490,992,819,905 is 4781431156320.
Find LCM of 929,490,992,819,905 with Prime Factorization
| 2 | 929, 490, 992, 819, 905 |
| 5 | 929, 245, 496, 819, 905 |
| 7 | 929, 49, 496, 819, 181 |
| 929, 7, 496, 117, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 929 x 7 x 496 x 117 x 181 = 4781431156320
Therefore, the lowest common multiple of 929,490,992,819,905 is 4781431156320.
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.
929 x 490 x 992 x 819 x 905 = 334700180942400
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.
929 : 1, 929
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 929,490,992,819,905, is 1.
Now, the common factors can be found like this.
929:929
490:2x 5x 7x 7
992:2x 2x 2x 2x 2x 31
819:3x 3x 7x 13
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 334700180942400/(1x70)
LCM = 334700180942400/70
LCM = 4781431156320
Thus, we can understand that the LCM of 929,490,992,819,905 is 4781431156320.
