HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 689, 104 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 689, 104 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 855, 689, 104 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 855, 689, 104 is 1.

HCF(855, 689, 104) = 1

Highest common factor (HCF) of 855, 689, 104 is 1.

Highest Common Factor of 855,689,104 using Euclid's algorithm

Highest Common Factor of 855,689,104 is 1

Step 1: Since 855 > 689, we apply the division lemma to 855 and 689, to get

855 = 689 x 1 + 166

Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 166 and 689, to get

689 = 166 x 4 + 25

Step 3: We consider the new divisor 166 and the new remainder 25, and apply the division lemma to get

166 = 25 x 6 + 16

We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get

25 = 16 x 1 + 9

We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get

16 = 9 x 1 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 855 and 689 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(166,25) = HCF(689,166) = HCF(855,689) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 104 > 1, we apply the division lemma to 104 and 1, to get

104 = 1 x 104 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 104 is 1

Notice that 1 = HCF(104,1) .
