Given numbers are 455,784,851,969,371
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,784,851,969,371 is 2227196964720.
Find LCM of 455,784,851,969,371 with Prime Factorization
| 7 | 455, 784, 851, 969, 371 |
| 65, 112, 851, 969, 53 |
Multiply the prime numbers at the bottom and the left side.
7 x 65 x 112 x 851 x 969 x 53 = 2227196964720
Therefore, the lowest common multiple of 455,784,851,969,371 is 2227196964720.
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.
455 x 784 x 851 x 969 x 371 = 109132651271280
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
851 : 1, 23, 37, 851
969 : 1, 3, 17, 19, 51, 57, 323, 969
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,784,851,969,371, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
784:2x 2x 2x 2x 7x 7
851:23x 37
969:3x 17x 19
371:7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 109132651271280/(1x49)
LCM = 109132651271280/49
LCM = 2227196964720
Thus, we can understand that the LCM of 455,784,851,969,371 is 2227196964720.
