Given numbers are 445,101,801,973,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,101,801,973,642 is 84226840110.
Find LCM of 445,101,801,973,642 with Prime Factorization
| 3 | 445, 101, 801, 973, 642 |
| 89 | 445, 101, 267, 973, 214 |
| 5, 101, 3, 973, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 89 x 5 x 101 x 3 x 973 x 214 = 84226840110
Therefore, the lowest common multiple of 445,101,801,973,642 is 84226840110.
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.
445 x 101 x 801 x 973 x 642 = 22488566309370
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.
445 : 1, 5, 89, 445
101 : 1, 101
801 : 1, 3, 9, 89, 267, 801
973 : 1, 7, 139, 973
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,101,801,973,642, is 1.
Now, the common factors can be found like this.
445:5x 89
101:101
801:3x 3x 89
973:7x 139
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 89 = 267
Therefore, the value for common factors is 267.
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 = 22488566309370/(1x267)
LCM = 22488566309370/267
LCM = 84226840110
Thus, we can understand that the LCM of 445,101,801,973,642 is 84226840110.
