Given numbers are 671,456,993,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,456,993,354 is 5975405304.
Find LCM of 671,456,993,354 with Prime Factorization
| 2 | 671, 456, 993, 354 |
| 3 | 671, 228, 993, 177 |
| 671, 76, 331, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 671 x 76 x 331 x 59 = 5975405304
Therefore, the lowest common multiple of 671,456,993,354 is 5975405304.
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.
671 x 456 x 993 x 354 = 107557295472
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.
671 : 1, 11, 61, 671
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
993 : 1, 3, 331, 993
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,456,993,354, is 1.
Now, the common factors can be found like this.
671:11x 61
456:2x 2x 2x 3x 19
993:3x 331
354:2x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 107557295472/(1x18)
LCM = 107557295472/18
LCM = 5975405304
Thus, we can understand that the LCM of 671,456,993,354 is 5975405304.
