Given numbers are 906,440,786,681,674
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,440,786,681,674 is 1997459269080.
Find LCM of 906,440,786,681,674 with Prime Factorization
| 2 | 906, 440, 786, 681, 674 |
| 3 | 453, 220, 393, 681, 337 |
| 151, 220, 131, 227, 337 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 220 x 131 x 227 x 337 = 1997459269080
Therefore, the lowest common multiple of 906,440,786,681,674 is 1997459269080.
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.
906 x 440 x 786 x 681 x 674 = 143817067373760
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
786 : 1, 2, 3, 6, 131, 262, 393, 786
681 : 1, 3, 227, 681
674 : 1, 2, 337, 674
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,440,786,681,674, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
440:2x 2x 2x 5x 11
786:2x 3x 131
681:3x 227
674:2x 337
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 143817067373760/(1x72)
LCM = 143817067373760/72
LCM = 1997459269080
Thus, we can understand that the LCM of 906,440,786,681,674 is 1997459269080.
