Given numbers are 674,893,145,456,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,893,145,456,748 is 195840365160.
Find LCM of 674,893,145,456,748 with Prime Factorization
| 2 | 674, 893, 145, 456, 748 |
| 2 | 337, 893, 145, 228, 374 |
| 19 | 337, 893, 145, 114, 187 |
| 337, 47, 145, 6, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 337 x 47 x 145 x 6 x 187 = 195840365160
Therefore, the lowest common multiple of 674,893,145,456,748 is 195840365160.
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.
674 x 893 x 145 x 456 x 748 = 29767735504320
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.
674 : 1, 2, 337, 674
893 : 1, 19, 47, 893
145 : 1, 5, 29, 145
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,893,145,456,748, is 1.
Now, the common factors can be found like this.
674:2x 337
893:19x 47
145:5x 29
456:2x 2x 2x 3x 19
748:2x 2x 11x 17
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 2x 19 = 152
Therefore, the value for common factors is 152.
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 = 29767735504320/(1x152)
LCM = 29767735504320/152
LCM = 195840365160
Thus, we can understand that the LCM of 674,893,145,456,748 is 195840365160.
