HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 51, 145, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 84, 51, 145, 968 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 84, 51, 145, 968 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 84, 51, 145, 968 is 1.

HCF(84, 51, 145, 968) = 1

HCF of 84, 51, 145, 968 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 84, 51, 145, 968 is 1.

Highest Common Factor of 84,51,145,968 using Euclid's algorithm

Highest Common Factor of 84,51,145,968 is 1

Step 1: Since 84 > 51, we apply the division lemma to 84 and 51, to get

84 = 51 x 1 + 33

Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 33 and 51, to get

51 = 33 x 1 + 18

Step 3: We consider the new divisor 33 and the new remainder 18, and apply the division lemma to get

33 = 18 x 1 + 15

We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get

18 = 15 x 1 + 3

We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 84 and 51 is 3

Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(33,18) = HCF(51,33) = HCF(84,51) .


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

Step 1: Since 145 > 3, we apply the division lemma to 145 and 3, to get

145 = 3 x 48 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 145 is 1

Notice that 1 = HCF(3,1) = HCF(145,3) .


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

Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get

968 = 1 x 968 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1

Notice that 1 = HCF(968,1) .
