Given numbers are 649,140,534,680,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,140,534,680,940 is 38766872760.
Find LCM of 649,140,534,680,940 with Prime Factorization
| 2 | 649, 140, 534, 680, 940 |
| 2 | 649, 70, 267, 340, 470 |
| 5 | 649, 35, 267, 170, 235 |
| 649, 7, 267, 34, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 649 x 7 x 267 x 34 x 47 = 38766872760
Therefore, the lowest common multiple of 649,140,534,680,940 is 38766872760.
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.
649 x 140 x 534 x 680 x 940 = 31013498208000
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.
649 : 1, 11, 59, 649
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
534 : 1, 2, 3, 6, 89, 178, 267, 534
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,140,534,680,940, is 1.
Now, the common factors can be found like this.
649:11x 59
140:2x 2x 5x 7
534:2x 3x 89
680:2x 2x 2x 5x 17
940:2x 2x 5x 47
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 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 31013498208000/(1x800)
LCM = 31013498208000/800
LCM = 38766872760
Thus, we can understand that the LCM of 649,140,534,680,940 is 38766872760.
