Find LCM of 821,156,884,962,554 with Prime Factorization
| 2 | 821, 156, 884, 962, 554 |
| 2 | 821, 78, 442, 481, 277 |
| 13 | 821, 39, 221, 481, 277 |
| 821, 3, 17, 37, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 821 x 3 x 17 x 37 x 277 = 22315065708
Therefore, the lowest common multiple of 821,156,884,962,554 is 22315065708.
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.
821 x 156 x 884 x 962 x 554 = 60339937674432
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.
821 : 1, 821
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
962 : 1, 2, 13, 26, 37, 74, 481, 962
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,156,884,962,554, is 1.
Now, the common factors can be found like this.
821:821
156:2x 2x 3x 13
884:2x 2x 13x 17
962:2x 13x 37
554:2x 277
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 13x 13 = 2704
Therefore, the value for common factors is 2704.
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 = 60339937674432/(1x2704)
LCM = 60339937674432/2704
LCM = 22315065708
Thus, we can understand that the LCM of 821,156,884,962,554 is 22315065708.
