Given numbers are 778,672,707,665,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,672,707,665,404 is 2508209760.
Find LCM of 778,672,707,665,404 with Prime Factorization
| 2 | 778, 672, 707, 665, 404 |
| 2 | 389, 336, 707, 665, 202 |
| 7 | 389, 168, 707, 665, 101 |
| 101 | 389, 24, 101, 95, 101 |
| 389, 24, 1, 95, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 101 x 389 x 24 x 1 x 95 x 1 = 2508209760
Therefore, the lowest common multiple of 778,672,707,665,404 is 2508209760.
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.
778 x 672 x 707 x 665 x 404 = 99305040817920
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.
778 : 1, 2, 389, 778
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
707 : 1, 7, 101, 707
665 : 1, 5, 7, 19, 35, 95, 133, 665
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,672,707,665,404, is 1.
Now, the common factors can be found like this.
778:2x 389
672:2x 2x 2x 2x 2x 3x 7
707:7x 101
665:5x 7x 19
404:2x 2x 101
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 2x 7x 7x 101 = 39592
Therefore, the value for common factors is 39592.
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 = 99305040817920/(1x39592)
LCM = 99305040817920/39592
LCM = 2508209760
Thus, we can understand that the LCM of 778,672,707,665,404 is 2508209760.
