Given numbers are 426,695,802,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,695,802,401 is 118724070.
Find LCM of 426,695,802,401 with Prime Factorization
| 2 | 426, 695, 802, 401 |
| 401 | 213, 695, 401, 401 |
| 213, 695, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 401 x 213 x 695 x 1 x 1 = 118724070
Therefore, the lowest common multiple of 426,695,802,401 is 118724070.
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.
426 x 695 x 802 x 401 = 95216704140
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
695 : 1, 5, 139, 695
802 : 1, 2, 401, 802
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,695,802,401, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
695:5x 139
802:2x 401
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 401 = 802
Therefore, the value for common factors is 802.
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 = 95216704140/(1x802)
LCM = 95216704140/802
LCM = 118724070
Thus, we can understand that the LCM of 426,695,802,401 is 118724070.
