HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 825, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 653, 825, 386 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 653, 825, 386 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 653, 825, 386 is 1.

HCF(653, 825, 386) = 1

Highest common factor (HCF) of 653, 825, 386 is 1.

Highest Common Factor of 653,825,386 using Euclid's algorithm

Highest Common Factor of 653,825,386 is 1

Step 1: Since 825 > 653, we apply the division lemma to 825 and 653, to get

825 = 653 x 1 + 172

Step 2: Since the reminder 653 ≠ 0, we apply division lemma to 172 and 653, to get

653 = 172 x 3 + 137

Step 3: We consider the new divisor 172 and the new remainder 137, and apply the division lemma to get

172 = 137 x 1 + 35

We consider the new divisor 137 and the new remainder 35,and apply the division lemma to get

137 = 35 x 3 + 32

We consider the new divisor 35 and the new remainder 32,and apply the division lemma to get

35 = 32 x 1 + 3

We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get

32 = 3 x 10 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 653 and 825 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(35,32) = HCF(137,35) = HCF(172,137) = HCF(653,172) = HCF(825,653) .

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

Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get

386 = 1 x 386 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1

Notice that 1 = HCF(386,1) .
