Given numbers are 987,697,643,134,790

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

The LCM of 987,697,643,134,790 is 23413309046610.

Find LCM of 987,697,643,134,790 with Prime Factorization

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

2 x 987 x 697 x 643 x 67 x 395 = 23413309046610

Therefore, the lowest common multiple of 987,697,643,134,790 is 23413309046610.

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.

987 x 697 x 643 x 134 x 790 = 46826618093220

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

697 : 1, 17, 41, 697

643 : 1, 643

134 : 1, 2, 67, 134

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,697,643,134,790, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

697:17x 41

643:643

134:2x 67

790:2x 5x 79

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 46826618093220/(1x2)

LCM = 46826618093220/2

LCM = 23413309046610

Thus, we can understand that the LCM of 987,697,643,134,790 is 23413309046610.
