Given numbers are 681,688,724,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,688,724,764 is 16197481488.
Find LCM of 681,688,724,764 with Prime Factorization
2 | 681, 688, 724, 764 |
2 | 681, 344, 362, 382 |
681, 172, 181, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 681 x 172 x 181 x 191 = 16197481488
Therefore, the lowest common multiple of 681,688,724,764 is 16197481488.
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.
681 x 688 x 724 x 764 = 259159703808
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.
681 : 1, 3, 227, 681
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
724 : 1, 2, 4, 181, 362, 724
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,688,724,764, is 1.
Now, the common factors can be found like this.
681:3x 227
688:2x 2x 2x 2x 43
724:2x 2x 181
764:2x 2x 191
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 2 = 16
Therefore, the value for common factors is 16.
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 = 259159703808/(1x16)
LCM = 259159703808/16
LCM = 16197481488
Thus, we can understand that the LCM of 681,688,724,764 is 16197481488.
