Find LCM of 976,621,427,782,342 with Prime Factorization
| 2 | 976, 621, 427, 782, 342 |
| 3 | 488, 621, 427, 391, 171 |
| 3 | 488, 207, 427, 391, 57 |
| 23 | 488, 69, 427, 391, 19 |
| 61 | 488, 3, 427, 17, 19 |
| 8, 3, 7, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 61 x 8 x 3 x 7 x 17 x 19 = 1370383056
Therefore, the lowest common multiple of 976,621,427,782,342 is 1370383056.
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.
976 x 621 x 427 x 782 x 342 = 69215307392448
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
621 : 1, 3, 9, 23, 27, 69, 207, 621
427 : 1, 7, 61, 427
782 : 1, 2, 17, 23, 34, 46, 391, 782
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,621,427,782,342, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
621:3x 3x 3x 23
427:7x 61
782:2x 17x 23
342:2x 3x 3x 19
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 3x 3x 23x 61 = 50508
Therefore, the value for common factors is 50508.
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 = 69215307392448/(1x50508)
LCM = 69215307392448/50508
LCM = 1370383056
Thus, we can understand that the LCM of 976,621,427,782,342 is 1370383056.
