Given numbers are 921,456,453,737,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,456,453,737,390 is 1012653830760.
Find LCM of 921,456,453,737,390 with Prime Factorization
2 | 921, 456, 453, 737, 390 |
3 | 921, 228, 453, 737, 195 |
307, 76, 151, 737, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 76 x 151 x 737 x 65 = 1012653830760
Therefore, the lowest common multiple of 921,456,453,737,390 is 1012653830760.
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.
921 x 456 x 453 x 737 x 390 = 54683306861040
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.
921 : 1, 3, 307, 921
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
453 : 1, 3, 151, 453
737 : 1, 11, 67, 737
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,456,453,737,390, is 1.
Now, the common factors can be found like this.
921:3x 307
456:2x 2x 2x 3x 19
453:3x 151
737:11x 67
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 54683306861040/(1x54)
LCM = 54683306861040/54
LCM = 1012653830760
Thus, we can understand that the LCM of 921,456,453,737,390 is 1012653830760.
