Find LCM of 638,247,434,708,186 with Prime Factorization
2 | 638, 247, 434, 708, 186 |
3 | 319, 247, 217, 354, 93 |
31 | 319, 247, 217, 118, 31 |
319, 247, 7, 118, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 319 x 247 x 7 x 118 x 1 = 12105441348
Therefore, the lowest common multiple of 638,247,434,708,186 is 12105441348.
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.
638 x 247 x 434 x 708 x 186 = 9006448362912
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
247 : 1, 13, 19, 247
434 : 1, 2, 7, 14, 31, 62, 217, 434
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,247,434,708,186, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
247:13x 19
434:2x 7x 31
708:2x 2x 3x 59
186:2x 3x 31
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 31 = 744
Therefore, the value for common factors is 744.
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 = 9006448362912/(1x744)
LCM = 9006448362912/744
LCM = 12105441348
Thus, we can understand that the LCM of 638,247,434,708,186 is 12105441348.
