HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 915, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 684, 915, 775 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 684, 915, 775 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 684, 915, 775 is 1.

HCF(684, 915, 775) = 1

Highest common factor (HCF) of 684, 915, 775 is 1.

Highest Common Factor of 684,915,775 using Euclid's algorithm

Highest Common Factor of 684,915,775 is 1

Step 1: Since 915 > 684, we apply the division lemma to 915 and 684, to get

915 = 684 x 1 + 231

Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 231 and 684, to get

684 = 231 x 2 + 222

Step 3: We consider the new divisor 231 and the new remainder 222, and apply the division lemma to get

231 = 222 x 1 + 9

We consider the new divisor 222 and the new remainder 9,and apply the division lemma to get

222 = 9 x 24 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 684 and 915 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(222,9) = HCF(231,222) = HCF(684,231) = HCF(915,684) .

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

Step 1: Since 775 > 3, we apply the division lemma to 775 and 3, to get

775 = 3 x 258 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 775 is 1

Notice that 1 = HCF(3,1) = HCF(775,3) .
