Given numbers are 920,421,765,965,110
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,421,765,965,110 is 125808895080.
Find LCM of 920,421,765,965,110 with Prime Factorization
| 2 | 920, 421, 765, 965, 110 |
| 5 | 460, 421, 765, 965, 55 |
| 92, 421, 153, 193, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 92 x 421 x 153 x 193 x 11 = 125808895080
Therefore, the lowest common multiple of 920,421,765,965,110 is 125808895080.
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.
920 x 421 x 765 x 965 x 110 = 31452223770000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
421 : 1, 421
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
965 : 1, 5, 193, 965
110 : 1, 2, 5, 10, 11, 22, 55, 110
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,421,765,965,110, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
421:421
765:3x 3x 5x 17
965:5x 193
110:2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 31452223770000/(1x250)
LCM = 31452223770000/250
LCM = 125808895080
Thus, we can understand that the LCM of 920,421,765,965,110 is 125808895080.
