Given numbers are 676,672,724,742,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,672,724,742,802 is 436872587424.
Find LCM of 676,672,724,742,802 with Prime Factorization
| 2 | 676, 672, 724, 742, 802 |
| 2 | 338, 336, 362, 371, 401 |
| 7 | 169, 168, 181, 371, 401 |
| 169, 24, 181, 53, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 169 x 24 x 181 x 53 x 401 = 436872587424
Therefore, the lowest common multiple of 676,672,724,742,802 is 436872587424.
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.
676 x 672 x 724 x 742 x 802 = 195718919165952
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
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
724 : 1, 2, 4, 181, 362, 724
742 : 1, 2, 7, 14, 53, 106, 371, 742
802 : 1, 2, 401, 802
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,672,724,742,802, is 2.
Now, the common factors can be found like this.
676:2x 2x 13x 13
672:2x 2x 2x 2x 2x 3x 7
724:2x 2x 181
742:2x 7x 53
802:2x 401
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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 195718919165952/(2x224)
LCM = 195718919165952/448
LCM = 436872587424
Thus, we can understand that the LCM of 676,672,724,742,802 is 436872587424.
