Given numbers are 892,653,630,465,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 892,653,630,465,138 is 130821197220.
Find LCM of 892,653,630,465,138 with Prime Factorization
| 2 | 892, 653, 630, 465, 138 |
| 3 | 446, 653, 315, 465, 69 |
| 5 | 446, 653, 105, 155, 23 |
| 446, 653, 21, 31, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 446 x 653 x 21 x 31 x 23 = 130821197220
Therefore, the lowest common multiple of 892,653,630,465,138 is 130821197220.
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.
892 x 653 x 630 x 465 x 138 = 23547815499600
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.
892 : 1, 2, 4, 223, 446, 892
653 : 1, 653
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
465 : 1, 3, 5, 15, 31, 93, 155, 465
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,653,630,465,138, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
653:653
630:2x 3x 3x 5x 7
465:3x 5x 31
138:2x 3x 23
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 5 = 180
Therefore, the value for common factors is 180.
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 = 23547815499600/(1x180)
LCM = 23547815499600/180
LCM = 130821197220
Thus, we can understand that the LCM of 892,653,630,465,138 is 130821197220.
