HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 975, 21, 890 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 823, 975, 21, 890 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 823, 975, 21, 890 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 823, 975, 21, 890 is 1.

HCF(823, 975, 21, 890) = 1

Highest common factor (HCF) of 823, 975, 21, 890 is 1.

Highest Common Factor of 823,975,21,890 using Euclid's algorithm

Highest Common Factor of 823,975,21,890 is 1

Step 1: Since 975 > 823, we apply the division lemma to 975 and 823, to get

975 = 823 x 1 + 152

Step 2: Since the reminder 823 ≠ 0, we apply division lemma to 152 and 823, to get

823 = 152 x 5 + 63

Step 3: We consider the new divisor 152 and the new remainder 63, and apply the division lemma to get

152 = 63 x 2 + 26

We consider the new divisor 63 and the new remainder 26,and apply the division lemma to get

63 = 26 x 2 + 11

We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get

26 = 11 x 2 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 823 and 975 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(63,26) = HCF(152,63) = HCF(823,152) = HCF(975,823) .

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

Step 1: Since 21 > 1, we apply the division lemma to 21 and 1, to get

21 = 1 x 21 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21 is 1

Notice that 1 = HCF(21,1) .

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

Step 1: Since 890 > 1, we apply the division lemma to 890 and 1, to get

890 = 1 x 890 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 890 is 1

Notice that 1 = HCF(890,1) .
