Given numbers are 821,194,274,632,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,194,274,632,680 is 586099650680.
Find LCM of 821,194,274,632,680 with Prime Factorization
| 2 | 821, 194, 274, 632, 680 |
| 2 | 821, 97, 137, 316, 340 |
| 2 | 821, 97, 137, 158, 170 |
| 821, 97, 137, 79, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 821 x 97 x 137 x 79 x 85 = 586099650680
Therefore, the lowest common multiple of 821,194,274,632,680 is 586099650680.
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.
821 x 194 x 274 x 632 x 680 = 18755188821760
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.
821 : 1, 821
194 : 1, 2, 97, 194
274 : 1, 2, 137, 274
632 : 1, 2, 4, 8, 79, 158, 316, 632
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,194,274,632,680, is 1.
Now, the common factors can be found like this.
821:821
194:2x 97
274:2x 137
632:2x 2x 2x 79
680:2x 2x 2x 5x 17
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 2 = 32
Therefore, the value for common factors is 32.
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 = 18755188821760/(1x32)
LCM = 18755188821760/32
LCM = 586099650680
Thus, we can understand that the LCM of 821,194,274,632,680 is 586099650680.
