Given numbers are 834,420,767,762,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,420,767,762,804 is 381011407140.
Find LCM of 834,420,767,762,804 with Prime Factorization
2 | 834, 420, 767, 762, 804 |
2 | 417, 210, 767, 381, 402 |
3 | 417, 105, 767, 381, 201 |
139, 35, 767, 127, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 35 x 767 x 127 x 67 = 381011407140
Therefore, the lowest common multiple of 834,420,767,762,804 is 381011407140.
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.
834 x 420 x 767 x 762 x 804 = 164596927884480
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
767 : 1, 13, 59, 767
762 : 1, 2, 3, 6, 127, 254, 381, 762
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,420,767,762,804, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
420:2x 2x 3x 5x 7
767:13x 59
762:2x 3x 127
804:2x 2x 3x 67
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 164596927884480/(1x432)
LCM = 164596927884480/432
LCM = 381011407140
Thus, we can understand that the LCM of 834,420,767,762,804 is 381011407140.
