Given numbers are 821,942,403,222
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,942,403,222 is 11531899002.
Find LCM of 821,942,403,222 with Prime Factorization
| 2 | 821, 942, 403, 222 |
| 3 | 821, 471, 403, 111 |
| 821, 157, 403, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 821 x 157 x 403 x 37 = 11531899002
Therefore, the lowest common multiple of 821,942,403,222 is 11531899002.
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 403 x 222 = 69191394012
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
403 : 1, 13, 31, 403
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,942,403,222, is 1.
Now, the common factors can be found like this.
821:821
942:2x 3x 157
403:13x 31
222:2x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 69191394012/(1x6)
LCM = 69191394012/6
LCM = 11531899002
Thus, we can understand that the LCM of 821,942,403,222 is 11531899002.
