Given numbers are 861,862,762,802,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,862,762,802,641 is 24227942839674.
Find LCM of 861,862,762,802,641 with Prime Factorization
| 2 | 861, 862, 762, 802, 641 |
| 3 | 861, 431, 381, 401, 641 |
| 287, 431, 127, 401, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 287 x 431 x 127 x 401 x 641 = 24227942839674
Therefore, the lowest common multiple of 861,862,762,802,641 is 24227942839674.
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.
861 x 862 x 762 x 802 x 641 = 290735314076088
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
862 : 1, 2, 431, 862
762 : 1, 2, 3, 6, 127, 254, 381, 762
802 : 1, 2, 401, 802
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,862,762,802,641, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
862:2x 431
762:2x 3x 127
802:2x 401
641:641
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 = 290735314076088/(1x12)
LCM = 290735314076088/12
LCM = 24227942839674
Thus, we can understand that the LCM of 861,862,762,802,641 is 24227942839674.
