Find LCM of 117,558,641,244,642 with Prime Factorization
2 | 117, 558, 641, 244, 642 |
3 | 117, 279, 641, 122, 321 |
3 | 39, 93, 641, 122, 107 |
13, 31, 641, 122, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 31 x 641 x 122 x 107 = 60698671956
Therefore, the lowest common multiple of 117,558,641,244,642 is 60698671956.
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.
117 x 558 x 641 x 244 x 642 = 6555456571248
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.
117 : 1, 3, 9, 13, 39, 117
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
641 : 1, 641
244 : 1, 2, 4, 61, 122, 244
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,558,641,244,642, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
558:2x 3x 3x 31
641:641
244:2x 2x 61
642:2x 3x 107
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 6555456571248/(1x108)
LCM = 6555456571248/108
LCM = 60698671956
Thus, we can understand that the LCM of 117,558,641,244,642 is 60698671956.
