Given numbers are 641,602,940,835,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,602,940,835,240 is 363454538160.
Find LCM of 641,602,940,835,240 with Prime Factorization
| 2 | 641, 602, 940, 835, 240 |
| 2 | 641, 301, 470, 835, 120 |
| 5 | 641, 301, 235, 835, 60 |
| 641, 301, 47, 167, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 641 x 301 x 47 x 167 x 12 = 363454538160
Therefore, the lowest common multiple of 641,602,940,835,240 is 363454538160.
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.
641 x 602 x 940 x 835 x 240 = 72690907632000
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.
641 : 1, 641
602 : 1, 2, 7, 14, 43, 86, 301, 602
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
835 : 1, 5, 167, 835
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,602,940,835,240, is 1.
Now, the common factors can be found like this.
641:641
602:2x 7x 43
940:2x 2x 5x 47
835:5x 167
240:2x 2x 2x 2x 3x 5
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 72690907632000/(1x200)
LCM = 72690907632000/200
LCM = 363454538160
Thus, we can understand that the LCM of 641,602,940,835,240 is 363454538160.
