Given numbers are 963,695,420,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,695,420,261 is 543459420.
Find LCM of 963,695,420,261 with Prime Factorization
3 | 963, 695, 420, 261 |
3 | 321, 695, 140, 87 |
5 | 107, 695, 140, 29 |
107, 139, 28, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 107 x 139 x 28 x 29 = 543459420
Therefore, the lowest common multiple of 963,695,420,261 is 543459420.
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.
963 x 695 x 420 x 261 = 73367021700
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.
963 : 1, 3, 9, 107, 321, 963
695 : 1, 5, 139, 695
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
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,695,420,261, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
695:5x 139
420:2x 2x 3x 5x 7
261:3x 3x 29
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 = 73367021700/(1x135)
LCM = 73367021700/135
LCM = 543459420
Thus, we can understand that the LCM of 963,695,420,261 is 543459420.
