Given numbers are 821,942,204,671,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,942,204,671,310 is 2734810226940.
Find LCM of 821,942,204,671,310 with Prime Factorization
2 | 821, 942, 204, 671, 310 |
3 | 821, 471, 102, 671, 155 |
821, 157, 34, 671, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 821 x 157 x 34 x 671 x 155 = 2734810226940
Therefore, the lowest common multiple of 821,942,204,671,310 is 2734810226940.
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 942 x 204 x 671 x 310 = 32817722723280
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
671 : 1, 11, 61, 671
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,942,204,671,310, is 1.
Now, the common factors can be found like this.
821:821
942:2x 3x 157
204:2x 2x 3x 17
671:11x 61
310:2x 5x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 32817722723280/(1x12)
LCM = 32817722723280/12
LCM = 2734810226940
Thus, we can understand that the LCM of 821,942,204,671,310 is 2734810226940.
