Find LCM of 842,956,472,312,286 with Prime Factorization
2 | 842, 956, 472, 312, 286 |
2 | 421, 478, 236, 156, 143 |
2 | 421, 239, 118, 78, 143 |
13 | 421, 239, 59, 39, 143 |
421, 239, 59, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 421 x 239 x 59 x 3 x 11 = 20374140072
Therefore, the lowest common multiple of 842,956,472,312,286 is 20374140072.
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.
842 x 956 x 472 x 312 x 286 = 33902569079808
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.
842 : 1, 2, 421, 842
956 : 1, 2, 4, 239, 478, 956
472 : 1, 2, 4, 8, 59, 118, 236, 472
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
286 : 1, 2, 11, 13, 22, 26, 143, 286
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,956,472,312,286, is 2.
Now, the common factors can be found like this.
842:2x 421
956:2x 2x 239
472:2x 2x 2x 59
312:2x 2x 2x 3x 13
286:2x 11x 13
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 2x 2x 13 = 832
Therefore, the value for common factors is 832.
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 = 33902569079808/(2x832)
LCM = 33902569079808/1664
LCM = 20374140072
Thus, we can understand that the LCM of 842,956,472,312,286 is 20374140072.
