Given numbers are 698,128,174,778

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 698,128,174,778 is 1511834496.

Find LCM of 698,128,174,778 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 349 x 64 x 87 x 389 = 1511834496

Therefore, the lowest common multiple of 698,128,174,778 is 1511834496.

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.

698 x 128 x 174 x 778 = 12094675968

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.

698 : 1, 2, 349, 698

128 : 1, 2, 4, 8, 16, 32, 64, 128

174 : 1, 2, 3, 6, 29, 58, 87, 174

778 : 1, 2, 389, 778

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,128,174,778, is 2.

Now, the common factors can be found like this.

698:2x 349

128:2x 2x 2x 2x 2x 2x 2

174:2x 3x 29

778:2x 389

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 = 12094675968/(2x4)

LCM = 12094675968/8

LCM = 1511834496

Thus, we can understand that the LCM of 698,128,174,778 is 1511834496.
