Given numbers are 938,220,397,932,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 938,220,397,932,784 is 267239089040.
Find LCM of 938,220,397,932,784 with Prime Factorization
| 2 | 938, 220, 397, 932, 784 |
| 2 | 469, 110, 397, 466, 392 |
| 7 | 469, 55, 397, 233, 196 |
| 67, 55, 397, 233, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 67 x 55 x 397 x 233 x 28 = 267239089040
Therefore, the lowest common multiple of 938,220,397,932,784 is 267239089040.
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.
938 x 220 x 397 x 932 x 784 = 59861555944960
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.
938 : 1, 2, 7, 14, 67, 134, 469, 938
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
397 : 1, 397
932 : 1, 2, 4, 233, 466, 932
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,220,397,932,784, is 1.
Now, the common factors can be found like this.
938:2x 7x 67
220:2x 2x 5x 11
397:397
932:2x 2x 233
784:2x 2x 2x 2x 7x 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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 59861555944960/(1x224)
LCM = 59861555944960/224
LCM = 267239089040
Thus, we can understand that the LCM of 938,220,397,932,784 is 267239089040.
