Given numbers are 863,665,570,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,665,570,621 is 712777590.
Find LCM of 863,665,570,621 with Prime Factorization
| 3 | 863, 665, 570, 621 |
| 5 | 863, 665, 190, 207 |
| 19 | 863, 133, 38, 207 |
| 863, 7, 2, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 863 x 7 x 2 x 207 = 712777590
Therefore, the lowest common multiple of 863,665,570,621 is 712777590.
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.
863 x 665 x 570 x 621 = 203141613150
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.
863 : 1, 863
665 : 1, 5, 7, 19, 35, 95, 133, 665
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,665,570,621, is 1.
Now, the common factors can be found like this.
863:863
665:5x 7x 19
570:2x 3x 5x 19
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19 = 285
Therefore, the value for common factors is 285.
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 = 203141613150/(1x285)
LCM = 203141613150/285
LCM = 712777590
Thus, we can understand that the LCM of 863,665,570,621 is 712777590.
