Find LCM of 691,208,708,520,834 with Prime Factorization
2 | 691, 208, 708, 520, 834 |
2 | 691, 104, 354, 260, 417 |
2 | 691, 52, 177, 130, 417 |
3 | 691, 26, 177, 65, 417 |
13 | 691, 26, 59, 65, 139 |
691, 2, 59, 5, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 691 x 2 x 59 x 5 x 139 = 17680699920
Therefore, the lowest common multiple of 691,208,708,520,834 is 17680699920.
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.
691 x 208 x 708 x 520 x 834 = 44131027000320
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.
691 : 1, 691
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,208,708,520,834, is 1.
Now, the common factors can be found like this.
691:691
208:2x 2x 2x 2x 13
708:2x 2x 3x 59
520:2x 2x 2x 5x 13
834:2x 3x 139
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 2x 2x 3x 13 = 2496
Therefore, the value for common factors is 2496.
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 = 44131027000320/(1x2496)
LCM = 44131027000320/2496
LCM = 17680699920
Thus, we can understand that the LCM of 691,208,708,520,834 is 17680699920.
