Find LCM of 685,665,152,372,709 with Prime Factorization
2 | 685, 665, 152, 372, 709 |
2 | 685, 665, 76, 186, 709 |
5 | 685, 665, 38, 93, 709 |
19 | 137, 133, 38, 93, 709 |
137, 7, 2, 93, 709 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 137 x 7 x 2 x 93 x 709 = 48057523080
Therefore, the lowest common multiple of 685,665,152,372,709 is 48057523080.
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.
685 x 665 x 152 x 372 x 709 = 18261858770400
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.
685 : 1, 5, 137, 685
665 : 1, 5, 7, 19, 35, 95, 133, 665
152 : 1, 2, 4, 8, 19, 38, 76, 152
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,665,152,372,709, is 1.
Now, the common factors can be found like this.
685:5x 137
665:5x 7x 19
152:2x 2x 2x 19
372:2x 2x 3x 31
709:709
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 18261858770400/(1x380)
LCM = 18261858770400/380
LCM = 48057523080
Thus, we can understand that the LCM of 685,665,152,372,709 is 48057523080.
