Given numbers are 962,240,681,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 962,240,681,420 is 183434160.
Find LCM of 962,240,681,420 with Prime Factorization
| 2 | 962, 240, 681, 420 |
| 2 | 481, 120, 681, 210 |
| 3 | 481, 60, 681, 105 |
| 5 | 481, 20, 227, 35 |
| 481, 4, 227, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 481 x 4 x 227 x 7 = 183434160
Therefore, the lowest common multiple of 962,240,681,420 is 183434160.
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.
962 x 240 x 681 x 420 = 66036297600
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.
962 : 1, 2, 13, 26, 37, 74, 481, 962
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
681 : 1, 3, 227, 681
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 962,240,681,420, is 1.
Now, the common factors can be found like this.
962:2x 13x 37
240:2x 2x 2x 2x 3x 5
681:3x 227
420:2x 2x 3x 5x 7
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 66036297600/(1x360)
LCM = 66036297600/360
LCM = 183434160
Thus, we can understand that the LCM of 962,240,681,420 is 183434160.
