Given numbers are 611,938,802,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,938,802,688 is 79058189392.
Find LCM of 611,938,802,688 with Prime Factorization
| 2 | 611, 938, 802, 688 |
| 611, 469, 401, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 611 x 469 x 401 x 344 = 79058189392
Therefore, the lowest common multiple of 611,938,802,688 is 79058189392.
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.
611 x 938 x 802 x 688 = 316232757568
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.
611 : 1, 13, 47, 611
938 : 1, 2, 7, 14, 67, 134, 469, 938
802 : 1, 2, 401, 802
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,938,802,688, is 1.
Now, the common factors can be found like this.
611:13x 47
938:2x 7x 67
802:2x 401
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 316232757568/(1x4)
LCM = 316232757568/4
LCM = 79058189392
Thus, we can understand that the LCM of 611,938,802,688 is 79058189392.
