HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 922, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 673, 922, 28 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 673, 922, 28 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 673, 922, 28 is 1.

HCF(673, 922, 28) = 1

Highest common factor (HCF) of 673, 922, 28 is 1.

Highest Common Factor of 673,922,28 using Euclid's algorithm

Highest Common Factor of 673,922,28 is 1

Step 1: Since 922 > 673, we apply the division lemma to 922 and 673, to get

922 = 673 x 1 + 249

Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 249 and 673, to get

673 = 249 x 2 + 175

Step 3: We consider the new divisor 249 and the new remainder 175, and apply the division lemma to get

249 = 175 x 1 + 74

We consider the new divisor 175 and the new remainder 74,and apply the division lemma to get

175 = 74 x 2 + 27

We consider the new divisor 74 and the new remainder 27,and apply the division lemma to get

74 = 27 x 2 + 20

We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get

27 = 20 x 1 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 922 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(74,27) = HCF(175,74) = HCF(249,175) = HCF(673,249) = HCF(922,673) .

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

Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1

Notice that 1 = HCF(28,1) .
