Given numbers are 149,128,697,146,690

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

The LCM of 149,128,697,146,690 is 334788839040.

Find LCM of 149,128,697,146,690 with Prime Factorization

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

2 x 149 x 64 x 697 x 73 x 345 = 334788839040

Therefore, the lowest common multiple of 149,128,697,146,690 is 334788839040.

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.

149 x 128 x 697 x 146 x 690 = 1339155356160

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.

149 : 1, 149

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

697 : 1, 17, 41, 697

146 : 1, 2, 73, 146

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,128,697,146,690, is 1.

Now, the common factors can be found like this.

149:149

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

697:17x 41

146:2x 73

690:2x 3x 5x 23

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 = 1339155356160/(1x4)

LCM = 1339155356160/4

LCM = 334788839040

Thus, we can understand that the LCM of 149,128,697,146,690 is 334788839040.
