Given numbers are 649,163,155,710,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,163,155,710,240 is 55880924880.
Find LCM of 649,163,155,710,240 with Prime Factorization
| 2 | 649, 163, 155, 710, 240 |
| 5 | 649, 163, 155, 355, 120 |
| 649, 163, 31, 71, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 649 x 163 x 31 x 71 x 24 = 55880924880
Therefore, the lowest common multiple of 649,163,155,710,240 is 55880924880.
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 163 x 155 x 710 x 240 = 2794046244000
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
163 : 1, 163
155 : 1, 5, 31, 155
710 : 1, 2, 5, 10, 71, 142, 355, 710
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 649,163,155,710,240, is 1.
Now, the common factors can be found like this.
649:11x 59
163:163
155:5x 31
710:2x 5x 71
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 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 2794046244000/(1x50)
LCM = 2794046244000/50
LCM = 55880924880
Thus, we can understand that the LCM of 649,163,155,710,240 is 55880924880.
