Given numbers are 546,700,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,700,641 is 17499300.
Find LCM of 546,700,641 with Prime Factorization
| 2 | 546, 700, 641 |
| 7 | 273, 350, 641 |
| 39, 50, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 39 x 50 x 641 = 17499300
Therefore, the lowest common multiple of 546,700,641 is 17499300.
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.
546 x 700 x 641 = 244990200
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,700,641, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
700:2x 2x 5x 5x 7
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 7 = 14
Therefore, the value for common factors is 14.
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 = 244990200/(1x14)
LCM = 244990200/14
LCM = 17499300
Thus, we can understand that the LCM of 546,700,641 is 17499300.
