Given numbers are 570,705,577,687,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,705,577,687,639 is 753986573910.
Find LCM of 570,705,577,687,639 with Prime Factorization
| 3 | 570, 705, 577, 687, 639 |
| 5 | 190, 235, 577, 229, 213 |
| 38, 47, 577, 229, 213 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 38 x 47 x 577 x 229 x 213 = 753986573910
Therefore, the lowest common multiple of 570,705,577,687,639 is 753986573910.
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.
570 x 705 x 577 x 687 x 639 = 101788187477850
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
705 : 1, 3, 5, 15, 47, 141, 235, 705
577 : 1, 577
687 : 1, 3, 229, 687
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,705,577,687,639, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
705:3x 5x 47
577:577
687:3x 229
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 101788187477850/(1x135)
LCM = 101788187477850/135
LCM = 753986573910
Thus, we can understand that the LCM of 570,705,577,687,639 is 753986573910.
