Given numbers are 452,749,409,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 452,749,409,638 is 44170696108.
Find LCM of 452,749,409,638 with Prime Factorization
| 2 | 452, 749, 409, 638 |
| 226, 749, 409, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 226 x 749 x 409 x 319 = 44170696108
Therefore, the lowest common multiple of 452,749,409,638 is 44170696108.
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.
452 x 749 x 409 x 638 = 88341392216
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.
452 : 1, 2, 4, 113, 226, 452
749 : 1, 7, 107, 749
409 : 1, 409
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,749,409,638, is 1.
Now, the common factors can be found like this.
452:2x 2x 113
749:7x 107
409:409
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 88341392216/(1x2)
LCM = 88341392216/2
LCM = 44170696108
Thus, we can understand that the LCM of 452,749,409,638 is 44170696108.
