Find LCM of 158,642,972,392,214 with Prime Factorization
2 | 158, 642, 972, 392, 214 |
2 | 79, 321, 486, 196, 107 |
3 | 79, 321, 243, 98, 107 |
107 | 79, 107, 81, 98, 107 |
79, 1, 81, 98, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 79 x 1 x 81 x 98 x 1 = 805198968
Therefore, the lowest common multiple of 158,642,972,392,214 is 805198968.
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.
158 x 642 x 972 x 392 x 214 = 8271003799296
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.
158 : 1, 2, 79, 158
642 : 1, 2, 3, 6, 107, 214, 321, 642
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
214 : 1, 2, 107, 214
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,642,972,392,214, is 2.
Now, the common factors can be found like this.
158:2x 79
642:2x 3x 107
972:2x 2x 3x 3x 3x 3x 3
392:2x 2x 2x 7x 7
214:2x 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 2x 2x 3x 107 = 5136
Therefore, the value for common factors is 5136.
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 = 8271003799296/(2x5136)
LCM = 8271003799296/10272
LCM = 805198968
Thus, we can understand that the LCM of 158,642,972,392,214 is 805198968.
