Given numbers are 969,157,282,905,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,157,282,905,840 is 362374720680.
Find LCM of 969,157,282,905,840 with Prime Factorization
| 2 | 969, 157, 282, 905, 840 |
| 3 | 969, 157, 141, 905, 420 |
| 5 | 323, 157, 47, 905, 140 |
| 323, 157, 47, 181, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 323 x 157 x 47 x 181 x 28 = 362374720680
Therefore, the lowest common multiple of 969,157,282,905,840 is 362374720680.
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.
969 x 157 x 282 x 905 x 840 = 32613724861200
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
157 : 1, 157
282 : 1, 2, 3, 6, 47, 94, 141, 282
905 : 1, 5, 181, 905
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,157,282,905,840, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
157:157
282:2x 3x 47
905:5x 181
840:2x 2x 2x 3x 5x 7
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 32613724861200/(1x90)
LCM = 32613724861200/90
LCM = 362374720680
Thus, we can understand that the LCM of 969,157,282,905,840 is 362374720680.
