Given numbers are 356,940,188,921,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 356,940,188,921,440 is 1695118920.
Find LCM of 356,940,188,921,440 with Prime Factorization
| 2 | 356, 940, 188, 921, 440 |
| 2 | 178, 470, 94, 921, 220 |
| 5 | 89, 235, 47, 921, 110 |
| 47 | 89, 47, 47, 921, 22 |
| 89, 1, 1, 921, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 47 x 89 x 1 x 1 x 921 x 22 = 1695118920
Therefore, the lowest common multiple of 356,940,188,921,440 is 1695118920.
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.
356 x 940 x 188 x 921 x 440 = 25494588556800
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.
356 : 1, 2, 4, 89, 178, 356
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
188 : 1, 2, 4, 47, 94, 188
921 : 1, 3, 307, 921
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 356,940,188,921,440, is 1.
Now, the common factors can be found like this.
356:2x 2x 89
940:2x 2x 5x 47
188:2x 2x 47
921:3x 307
440:2x 2x 2x 5x 11
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 2x 2x 2x 5x 47 = 15040
Therefore, the value for common factors is 15040.
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 = 25494588556800/(1x15040)
LCM = 25494588556800/15040
LCM = 1695118920
Thus, we can understand that the LCM of 356,940,188,921,440 is 1695118920.
