HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 643, 874, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 974, 643, 874, 193 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 974, 643, 874, 193 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 974, 643, 874, 193 is 1.

HCF(974, 643, 874, 193) = 1

Highest common factor (HCF) of 974, 643, 874, 193 is 1.

Highest Common Factor of 974,643,874,193 using Euclid's algorithm

Highest Common Factor of 974,643,874,193 is 1

Step 1: Since 974 > 643, we apply the division lemma to 974 and 643, to get

974 = 643 x 1 + 331

Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 331 and 643, to get

643 = 331 x 1 + 312

Step 3: We consider the new divisor 331 and the new remainder 312, and apply the division lemma to get

331 = 312 x 1 + 19

We consider the new divisor 312 and the new remainder 19,and apply the division lemma to get

312 = 19 x 16 + 8

We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get

19 = 8 x 2 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 974 and 643 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(312,19) = HCF(331,312) = HCF(643,331) = HCF(974,643) .


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

Step 1: Since 874 > 1, we apply the division lemma to 874 and 1, to get

874 = 1 x 874 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 874 is 1

Notice that 1 = HCF(874,1) .


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

Step 1: Since 193 > 1, we apply the division lemma to 193 and 1, to get

193 = 1 x 193 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 193 is 1

Notice that 1 = HCF(193,1) .
