Given numbers are 228,133,152,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,133,152,644 is 73416.
Find LCM of 228,133,152,644 with Prime Factorization
| 2 | 228, 133, 152, 644 |
| 2 | 114, 133, 76, 322 |
| 7 | 57, 133, 38, 161 |
| 19 | 57, 19, 38, 23 |
| 3, 1, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 3 x 1 x 2 x 23 = 73416
Therefore, the lowest common multiple of 228,133,152,644 is 73416.
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.
228 x 133 x 152 x 644 = 2968355712
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
133 : 1, 7, 19, 133
152 : 1, 2, 4, 8, 19, 38, 76, 152
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,133,152,644, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
133:7x 19
152:2x 2x 2x 19
644:2x 2x 7x 23
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 7x 19x 19 = 40432
Therefore, the value for common factors is 40432.
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 = 2968355712/(1x40432)
LCM = 2968355712/40432
LCM = 73416
Thus, we can understand that the LCM of 228,133,152,644 is 73416.
