HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 169, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 268, 169, 864 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 268, 169, 864 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 268, 169, 864 is 1.

HCF(268, 169, 864) = 1

Highest common factor (HCF) of 268, 169, 864 is 1.

Highest Common Factor of 268,169,864 using Euclid's algorithm

Highest Common Factor of 268,169,864 is 1

Step 1: Since 268 > 169, we apply the division lemma to 268 and 169, to get

268 = 169 x 1 + 99

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 99 and 169, to get

169 = 99 x 1 + 70

Step 3: We consider the new divisor 99 and the new remainder 70, and apply the division lemma to get

99 = 70 x 1 + 29

We consider the new divisor 70 and the new remainder 29,and apply the division lemma to get

70 = 29 x 2 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 268 and 169 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(99,70) = HCF(169,99) = HCF(268,169) .

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

Step 1: Since 864 > 1, we apply the division lemma to 864 and 1, to get

864 = 1 x 864 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 864 is 1

Notice that 1 = HCF(864,1) .
