Given numbers are 365,924,802,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 365,924,802,420 is 135241260.
Find LCM of 365,924,802,420 with Prime Factorization
| 2 | 365, 924, 802, 420 |
| 2 | 365, 462, 401, 210 |
| 3 | 365, 231, 401, 105 |
| 5 | 365, 77, 401, 35 |
| 7 | 73, 77, 401, 7 |
| 73, 11, 401, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 73 x 11 x 401 x 1 = 135241260
Therefore, the lowest common multiple of 365,924,802,420 is 135241260.
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.
365 x 924 x 802 x 420 = 113602658400
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.
365 : 1, 5, 73, 365
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
802 : 1, 2, 401, 802
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 365,924,802,420, is 1.
Now, the common factors can be found like this.
365:5x 73
924:2x 2x 3x 7x 11
802:2x 401
420:2x 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 2x 2x 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 113602658400/(1x840)
LCM = 113602658400/840
LCM = 135241260
Thus, we can understand that the LCM of 365,924,802,420 is 135241260.
