Given numbers are 185,748,905,623,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,748,905,623,640 is 499332606080.
Find LCM of 185,748,905,623,640 with Prime Factorization
| 2 | 185, 748, 905, 623, 640 |
| 2 | 185, 374, 905, 623, 320 |
| 5 | 185, 187, 905, 623, 160 |
| 37, 187, 181, 623, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 187 x 181 x 623 x 32 = 499332606080
Therefore, the lowest common multiple of 185,748,905,623,640 is 499332606080.
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.
185 x 748 x 905 x 623 x 640 = 49933260608000
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.
185 : 1, 5, 37, 185
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
905 : 1, 5, 181, 905
623 : 1, 7, 89, 623
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,748,905,623,640, is 1.
Now, the common factors can be found like this.
185:5x 37
748:2x 2x 11x 17
905:5x 181
623:7x 89
640:2x 2x 2x 2x 2x 2x 2x 5
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 49933260608000/(1x100)
LCM = 49933260608000/100
LCM = 499332606080
Thus, we can understand that the LCM of 185,748,905,623,640 is 499332606080.
