Given numbers are 220,398,692,597
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,398,692,597 is 22721820.
Find LCM of 220,398,692,597 with Prime Factorization
| 2 | 220, 398, 692, 597 |
| 2 | 110, 199, 346, 597 |
| 199 | 55, 199, 173, 597 |
| 55, 1, 173, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 199 x 55 x 1 x 173 x 3 = 22721820
Therefore, the lowest common multiple of 220,398,692,597 is 22721820.
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.
220 x 398 x 692 x 597 = 36173137440
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
398 : 1, 2, 199, 398
692 : 1, 2, 4, 173, 346, 692
597 : 1, 3, 199, 597
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,398,692,597, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
398:2x 199
692:2x 2x 173
597:3x 199
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 199 = 1592
Therefore, the value for common factors is 1592.
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 = 36173137440/(1x1592)
LCM = 36173137440/1592
LCM = 22721820
Thus, we can understand that the LCM of 220,398,692,597 is 22721820.
