Given numbers are 643,292,770,584
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,292,770,584 is 144572120.
Find LCM of 643,292,770,584 with Prime Factorization
2 | 643, 292, 770, 584 |
2 | 643, 146, 385, 292 |
73 | 643, 73, 385, 146 |
643, 1, 385, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 73 x 643 x 1 x 385 x 2 = 144572120
Therefore, the lowest common multiple of 643,292,770,584 is 144572120.
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.
643 x 292 x 770 x 584 = 84430118080
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.
643 : 1, 643
292 : 1, 2, 4, 73, 146, 292
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
584 : 1, 2, 4, 8, 73, 146, 292, 584
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,292,770,584, is 1.
Now, the common factors can be found like this.
643:643
292:2x 2x 73
770:2x 5x 7x 11
584:2x 2x 2x 73
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 73 = 584
Therefore, the value for common factors is 584.
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 = 84430118080/(1x584)
LCM = 84430118080/584
LCM = 144572120
Thus, we can understand that the LCM of 643,292,770,584 is 144572120.
