Given numbers are 642,835,829,350,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,835,829,350,560 is 124432568400.
Find LCM of 642,835,829,350,560 with Prime Factorization
| 2 | 642, 835, 829, 350, 560 |
| 5 | 321, 835, 829, 175, 280 |
| 7 | 321, 167, 829, 35, 56 |
| 321, 167, 829, 5, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 321 x 167 x 829 x 5 x 8 = 124432568400
Therefore, the lowest common multiple of 642,835,829,350,560 is 124432568400.
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.
642 x 835 x 829 x 350 x 560 = 87102797880000
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
835 : 1, 5, 167, 835
829 : 1, 829
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,835,829,350,560, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
835:5x 167
829:829
350:2x 5x 5x 7
560:2x 2x 2x 2x 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 5x 5x 7 = 700
Therefore, the value for common factors is 700.
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 = 87102797880000/(1x700)
LCM = 87102797880000/700
LCM = 124432568400
Thus, we can understand that the LCM of 642,835,829,350,560 is 124432568400.
