HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 295, 353 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 653, 295, 353 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, 295, 353 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, 295, 353 is 1.

HCF(653, 295, 353) = 1

Highest common factor (HCF) of 653, 295, 353 is 1.

Highest Common Factor of 653,295,353 using Euclid's algorithm

Highest Common Factor of 653,295,353 is 1

Step 1: Since 653 > 295, we apply the division lemma to 653 and 295, to get

653 = 295 x 2 + 63

Step 2: Since the reminder 295 ≠ 0, we apply division lemma to 63 and 295, to get

295 = 63 x 4 + 43

Step 3: We consider the new divisor 63 and the new remainder 43, and apply the division lemma to get

63 = 43 x 1 + 20

We consider the new divisor 43 and the new remainder 20,and apply the division lemma to get

43 = 20 x 2 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 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 295 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(43,20) = HCF(63,43) = HCF(295,63) = HCF(653,295) .

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

Step 1: Since 353 > 1, we apply the division lemma to 353 and 1, to get

353 = 1 x 353 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 353 is 1

Notice that 1 = HCF(353,1) .
