Given numbers are 874,692,418,780,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,692,418,780,641 is 415788867780.
Find LCM of 874,692,418,780,641 with Prime Factorization
| 2 | 874, 692, 418, 780, 641 |
| 2 | 437, 346, 209, 390, 641 |
| 19 | 437, 173, 209, 195, 641 |
| 23, 173, 11, 195, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 23 x 173 x 11 x 195 x 641 = 415788867780
Therefore, the lowest common multiple of 874,692,418,780,641 is 415788867780.
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.
874 x 692 x 418 x 780 x 641 = 126399815805120
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
692 : 1, 2, 4, 173, 346, 692
418 : 1, 2, 11, 19, 22, 38, 209, 418
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,692,418,780,641, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
692:2x 2x 173
418:2x 11x 19
780:2x 2x 3x 5x 13
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 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 126399815805120/(1x304)
LCM = 126399815805120/304
LCM = 415788867780
Thus, we can understand that the LCM of 874,692,418,780,641 is 415788867780.
