Given numbers are 924,456,188,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 924,456,188,438 is 120469272.
Find LCM of 924,456,188,438 with Prime Factorization
| 2 | 924, 456, 188, 438 |
| 2 | 462, 228, 94, 219 |
| 3 | 231, 114, 47, 219 |
| 77, 38, 47, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 77 x 38 x 47 x 73 = 120469272
Therefore, the lowest common multiple of 924,456,188,438 is 120469272.
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.
924 x 456 x 188 x 438 = 34695150336
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.
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
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
188 : 1, 2, 4, 47, 94, 188
438 : 1, 2, 3, 6, 73, 146, 219, 438
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,456,188,438, is 2.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
456:2x 2x 2x 3x 19
188:2x 2x 47
438:2x 3x 73
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 = 34695150336/(2x144)
LCM = 34695150336/288
LCM = 120469272
Thus, we can understand that the LCM of 924,456,188,438 is 120469272.
