Find LCM of 520,994,980,807,198 with Prime Factorization
| 2 | 520, 994, 980, 807, 198 |
| 2 | 260, 497, 490, 807, 99 |
| 3 | 130, 497, 245, 807, 99 |
| 5 | 130, 497, 245, 269, 33 |
| 7 | 26, 497, 49, 269, 33 |
| 26, 71, 7, 269, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 26 x 71 x 7 x 269 x 33 = 48177609480
Therefore, the lowest common multiple of 520,994,980,807,198 is 48177609480.
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.
520 x 994 x 980 x 807 x 198 = 80938383926400
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
994 : 1, 2, 7, 14, 71, 142, 497, 994
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
807 : 1, 3, 269, 807
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,994,980,807,198, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
994:2x 7x 71
980:2x 2x 5x 7x 7
807:3x 269
198:2x 3x 3x 11
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 2x 3x 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 80938383926400/(1x1680)
LCM = 80938383926400/1680
LCM = 48177609480
Thus, we can understand that the LCM of 520,994,980,807,198 is 48177609480.
