Find LCM of 771,980,207,147,105 with Prime Factorization
3 | 771, 980, 207, 147, 105 |
5 | 257, 980, 69, 49, 35 |
7 | 257, 196, 69, 49, 7 |
7 | 257, 28, 69, 1, 7 |
257, 4, 69, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 7 x 257 x 4 x 69 x 1 x 1 = 52135020
Therefore, the lowest common multiple of 771,980,207,147,105 is 52135020.
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.
771 x 980 x 207 x 147 x 105 = 2414112101100
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.
771 : 1, 3, 257, 771
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
207 : 1, 3, 9, 23, 69, 207
147 : 1, 3, 7, 21, 49, 147
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,980,207,147,105, is 1.
Now, the common factors can be found like this.
771:3x 257
980:2x 2x 5x 7x 7
207:3x 3x 23
147:3x 7x 7
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7x 7x 7 = 46305
Therefore, the value for common factors is 46305.
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 = 2414112101100/(1x46305)
LCM = 2414112101100/46305
LCM = 52135020
Thus, we can understand that the LCM of 771,980,207,147,105 is 52135020.
