The LCM of 453,421,120,680,895 is 23213586360.
Find LCM of 453,421,120,680,895 with Prime Factorization
| 2 | 453, 421, 120, 680, 895 |
| 2 | 453, 421, 60, 340, 895 |
| 2 | 453, 421, 30, 170, 895 |
| 3 | 453, 421, 15, 85, 895 |
| 5 | 151, 421, 5, 85, 895 |
| 151, 421, 1, 17, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 151 x 421 x 1 x 17 x 179 = 23213586360
Therefore, the lowest common multiple of 453,421,120,680,895 is 23213586360.
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.
453 x 421 x 120 x 680 x 895 = 13928151816000
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.
453 : 1, 3, 151, 453
421 : 1, 421
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,421,120,680,895, is 1.
Now, the common factors can be found like this.
453:3x 151
421:421
120:2x 2x 2x 3x 5
680:2x 2x 2x 5x 17
895:5x 179
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 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 13928151816000/(1x600)
LCM = 13928151816000/600
LCM = 23213586360
Thus, we can understand that the LCM of 453,421,120,680,895 is 23213586360.
