Given numbers are 695,690,756,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 695,690,756,549 is 737164260.
Find LCM of 695,690,756,549 with Prime Factorization
| 2 | 695, 690, 756, 549 |
| 3 | 695, 345, 378, 549 |
| 3 | 695, 115, 126, 183 |
| 5 | 695, 115, 42, 61 |
| 139, 23, 42, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 139 x 23 x 42 x 61 = 737164260
Therefore, the lowest common multiple of 695,690,756,549 is 737164260.
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.
695 x 690 x 756 x 549 = 199034350200
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.
695 : 1, 5, 139, 695
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,690,756,549, is 1.
Now, the common factors can be found like this.
695:5x 139
690:2x 3x 5x 23
756:2x 2x 3x 3x 3x 7
549:3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 199034350200/(1x270)
LCM = 199034350200/270
LCM = 737164260
Thus, we can understand that the LCM of 695,690,756,549 is 737164260.
