Given numbers are 468,942,749,456,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,942,749,456,890 is 930616890840.
Find LCM of 468,942,749,456,890 with Prime Factorization
| 2 | 468, 942, 749, 456, 890 |
| 2 | 234, 471, 749, 228, 445 |
| 3 | 117, 471, 749, 114, 445 |
| 39, 157, 749, 38, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 39 x 157 x 749 x 38 x 445 = 930616890840
Therefore, the lowest common multiple of 468,942,749,456,890 is 930616890840.
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.
468 x 942 x 749 x 456 x 890 = 134008832280960
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
942 : 1, 2, 3, 6, 157, 314, 471, 942
749 : 1, 7, 107, 749
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,942,749,456,890, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
942:2x 3x 157
749:7x 107
456:2x 2x 2x 3x 19
890:2x 5x 89
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 134008832280960/(1x144)
LCM = 134008832280960/144
LCM = 930616890840
Thus, we can understand that the LCM of 468,942,749,456,890 is 930616890840.
