Given numbers are 354,798,403,931,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,798,403,931,478 is 31743578958.
Find LCM of 354,798,403,931,478 with Prime Factorization
| 2 | 354, 798, 403, 931, 478 |
| 3 | 177, 399, 403, 931, 239 |
| 7 | 59, 133, 403, 931, 239 |
| 19 | 59, 19, 403, 133, 239 |
| 59, 1, 403, 7, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 59 x 1 x 403 x 7 x 239 = 31743578958
Therefore, the lowest common multiple of 354,798,403,931,478 is 31743578958.
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.
354 x 798 x 403 x 931 x 478 = 50662752016968
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
403 : 1, 13, 31, 403
931 : 1, 7, 19, 49, 133, 931
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,798,403,931,478, is 1.
Now, the common factors can be found like this.
354:2x 3x 59
798:2x 3x 7x 19
403:13x 31
931:7x 7x 19
478:2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7x 19 = 1596
Therefore, the value for common factors is 1596.
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 = 50662752016968/(1x1596)
LCM = 50662752016968/1596
LCM = 31743578958
Thus, we can understand that the LCM of 354,798,403,931,478 is 31743578958.
