Find LCM of 690,736,411,985,690 with Prime Factorization
| 2 | 690, 736, 411, 985, 690 |
| 3 | 345, 368, 411, 985, 345 |
| 5 | 115, 368, 137, 985, 115 |
| 23 | 23, 368, 137, 197, 23 |
| 1, 16, 137, 197, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 1 x 16 x 137 x 197 x 1 = 297958560
Therefore, the lowest common multiple of 690,736,411,985,690 is 297958560.
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.
690 x 736 x 411 x 985 x 690 = 141858070416000
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
411 : 1, 3, 137, 411
985 : 1, 5, 197, 985
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,736,411,985,690, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
736:2x 2x 2x 2x 2x 23
411:3x 137
985:5x 197
690:2x 3x 5x 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 5x 5x 23x 23 = 476100
Therefore, the value for common factors is 476100.
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 = 141858070416000/(1x476100)
LCM = 141858070416000/476100
LCM = 297958560
Thus, we can understand that the LCM of 690,736,411,985,690 is 297958560.
