Given numbers are 778,689,195,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,689,195,557 is 4478630910.
Find LCM of 778,689,195,557 with Prime Factorization
13 | 778, 689, 195, 557 |
778, 53, 15, 557 |
Multiply the prime numbers at the bottom and the left side.
13 x 778 x 53 x 15 x 557 = 4478630910
Therefore, the lowest common multiple of 778,689,195,557 is 4478630910.
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.
778 x 689 x 195 x 557 = 58222201830
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.
778 : 1, 2, 389, 778
689 : 1, 13, 53, 689
195 : 1, 3, 5, 13, 15, 39, 65, 195
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,689,195,557, is 1.
Now, the common factors can be found like this.
778:2x 389
689:13x 53
195:3x 5x 13
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 58222201830/(1x13)
LCM = 58222201830/13
LCM = 4478630910
Thus, we can understand that the LCM of 778,689,195,557 is 4478630910.
