Given numbers are 631,553,147,343,377
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,553,147,343,377 is 19338072117.
Find LCM of 631,553,147,343,377 with Prime Factorization
| 7 | 631, 553, 147, 343, 377 |
| 7 | 631, 79, 21, 49, 377 |
| 631, 79, 3, 7, 377 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 631 x 79 x 3 x 7 x 377 = 19338072117
Therefore, the lowest common multiple of 631,553,147,343,377 is 19338072117.
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.
631 x 553 x 147 x 343 x 377 = 6632958736131
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.
631 : 1, 631
553 : 1, 7, 79, 553
147 : 1, 3, 7, 21, 49, 147
343 : 1, 7, 49, 343
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,553,147,343,377, is 1.
Now, the common factors can be found like this.
631:631
553:7x 79
147:3x 7x 7
343:7x 7x 7
377:13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 7 = 343
Therefore, the value for common factors is 343.
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 = 6632958736131/(1x343)
LCM = 6632958736131/343
LCM = 19338072117
Thus, we can understand that the LCM of 631,553,147,343,377 is 19338072117.
