Given numbers are 280,491,938,276,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,491,938,276,146 is 46396612920.
Find LCM of 280,491,938,276,146 with Prime Factorization
2 | 280, 491, 938, 276, 146 |
2 | 140, 491, 469, 138, 73 |
7 | 70, 491, 469, 69, 73 |
10, 491, 67, 69, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 10 x 491 x 67 x 69 x 73 = 46396612920
Therefore, the lowest common multiple of 280,491,938,276,146 is 46396612920.
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.
280 x 491 x 938 x 276 x 146 = 5196420647040
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
491 : 1, 491
938 : 1, 2, 7, 14, 67, 134, 469, 938
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,491,938,276,146, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
491:491
938:2x 7x 67
276:2x 2x 3x 23
146:2x 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 7 = 112
Therefore, the value for common factors is 112.
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 = 5196420647040/(1x112)
LCM = 5196420647040/112
LCM = 46396612920
Thus, we can understand that the LCM of 280,491,938,276,146 is 46396612920.
