The LCM of 770,176,679,987 is 84250320.

Find LCM of 770,176,679,987 with Prime Factorization


2 770, 176, 679, 987
7 385, 88, 679, 987
11 55, 88, 97, 141
5, 8, 97, 141

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

2 x 7 x 11 x 5 x 8 x 97 x 141 = 84250320

Therefore, the lowest common multiple of 770,176,679,987 is 84250320.

LCM Formula to Find Lowest Common Multiple of 770,176,679,987

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.

770 x 176 x 679 x 987 = 90821844960

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

679 : 1, 7, 97, 679

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,176,679,987, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

176:2x 2x 2x 2x 11

679:7x 97

987:3x 7x 47

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

2x 7x 7x 11 = 1078

Therefore, the value for common factors is 1078.

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 = 90821844960/(1x1078)

LCM = 90821844960/1078

LCM = 84250320

Thus, we can understand that the LCM of 770,176,679,987 is 84250320.
