Given numbers are 224,390,852,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 224,390,852,781 is 34114080.
Find LCM of 224,390,852,781 with Prime Factorization
| 2 | 224, 390, 852, 781 |
| 2 | 112, 195, 426, 781 |
| 3 | 56, 195, 213, 781 |
| 71 | 56, 65, 71, 781 |
| 56, 65, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 71 x 56 x 65 x 1 x 11 = 34114080
Therefore, the lowest common multiple of 224,390,852,781 is 34114080.
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.
224 x 390 x 852 x 781 = 58130392320
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.
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 224,390,852,781, is 1.
Now, the common factors can be found like this.
224:2x 2x 2x 2x 2x 7
390:2x 3x 5x 13
852:2x 2x 3x 71
781:11x 71
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 71 = 1704
Therefore, the value for common factors is 1704.
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 = 58130392320/(1x1704)
LCM = 58130392320/1704
LCM = 34114080
Thus, we can understand that the LCM of 224,390,852,781 is 34114080.
