Given numbers are 785,320,612,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,320,612,894 is 1145321280.
Find LCM of 785,320,612,894 with Prime Factorization
2 | 785, 320, 612, 894 |
2 | 785, 160, 306, 447 |
3 | 785, 80, 153, 447 |
5 | 785, 80, 51, 149 |
157, 16, 51, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 157 x 16 x 51 x 149 = 1145321280
Therefore, the lowest common multiple of 785,320,612,894 is 1145321280.
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.
785 x 320 x 612 x 894 = 137438553600
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.
785 : 1, 5, 157, 785
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,320,612,894, is 1.
Now, the common factors can be found like this.
785:5x 157
320:2x 2x 2x 2x 2x 2x 5
612:2x 2x 3x 3x 17
894:2x 3x 149
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 137438553600/(1x120)
LCM = 137438553600/120
LCM = 1145321280
Thus, we can understand that the LCM of 785,320,612,894 is 1145321280.
