Given numbers are 478,975,868,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,975,868,615 is 8292893700.
Find LCM of 478,975,868,615 with Prime Factorization
| 2 | 478, 975, 868, 615 |
| 3 | 239, 975, 434, 615 |
| 5 | 239, 325, 434, 205 |
| 239, 65, 434, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 239 x 65 x 434 x 41 = 8292893700
Therefore, the lowest common multiple of 478,975,868,615 is 8292893700.
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.
478 x 975 x 868 x 615 = 248786811000
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.
478 : 1, 2, 239, 478
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,975,868,615, is 1.
Now, the common factors can be found like this.
478:2x 239
975:3x 5x 5x 13
868:2x 2x 7x 31
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 248786811000/(1x30)
LCM = 248786811000/30
LCM = 8292893700
Thus, we can understand that the LCM of 478,975,868,615 is 8292893700.
