Given numbers are 928,634,893,659,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 928,634,893,659,420 is 18177468929760.
Find LCM of 928,634,893,659,420 with Prime Factorization
| 2 | 928, 634, 893, 659, 420 |
| 2 | 464, 317, 893, 659, 210 |
| 232, 317, 893, 659, 105 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 232 x 317 x 893 x 659 x 105 = 18177468929760
Therefore, the lowest common multiple of 928,634,893,659,420 is 18177468929760.
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.
928 x 634 x 893 x 659 x 420 = 145419751438080
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
634 : 1, 2, 317, 634
893 : 1, 19, 47, 893
659 : 1, 659
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,634,893,659,420, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
634:2x 317
893:19x 47
659:659
420:2x 2x 3x 5x 7
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 2 = 8
Therefore, the value for common factors is 8.
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 = 145419751438080/(1x8)
LCM = 145419751438080/8
LCM = 18177468929760
Thus, we can understand that the LCM of 928,634,893,659,420 is 18177468929760.
