Given numbers are 855,101,745,578,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,101,745,578,290 is 215674893990.
Find LCM of 855,101,745,578,290 with Prime Factorization
| 2 | 855, 101, 745, 578, 290 |
| 5 | 855, 101, 745, 289, 145 |
| 171, 101, 149, 289, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 171 x 101 x 149 x 289 x 29 = 215674893990
Therefore, the lowest common multiple of 855,101,745,578,290 is 215674893990.
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.
855 x 101 x 745 x 578 x 290 = 10783744699500
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
101 : 1, 101
745 : 1, 5, 149, 745
578 : 1, 2, 17, 34, 289, 578
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,101,745,578,290, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
101:101
745:5x 149
578:2x 17x 17
290:2x 5x 29
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 5 = 50
Therefore, the value for common factors is 50.
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 = 10783744699500/(1x50)
LCM = 10783744699500/50
LCM = 215674893990
Thus, we can understand that the LCM of 855,101,745,578,290 is 215674893990.
