HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 978, 78, 632 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 905, 978, 78, 632 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 905, 978, 78, 632 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 905, 978, 78, 632 is 1.

HCF(905, 978, 78, 632) = 1

HCF of 905, 978, 78, 632 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 905, 978, 78, 632 is 1.

Highest Common Factor of 905,978,78,632 using Euclid's algorithm

Highest Common Factor of 905,978,78,632 is 1

Step 1: Since 978 > 905, we apply the division lemma to 978 and 905, to get

978 = 905 x 1 + 73

Step 2: Since the reminder 905 ≠ 0, we apply division lemma to 73 and 905, to get

905 = 73 x 12 + 29

Step 3: We consider the new divisor 73 and the new remainder 29, and apply the division lemma to get

73 = 29 x 2 + 15

We consider the new divisor 29 and the new remainder 15,and apply the division lemma to get

29 = 15 x 1 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 905 and 978 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(73,29) = HCF(905,73) = HCF(978,905) .


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

Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get

78 = 1 x 78 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1

Notice that 1 = HCF(78,1) .


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

Step 1: Since 632 > 1, we apply the division lemma to 632 and 1, to get

632 = 1 x 632 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 632 is 1

Notice that 1 = HCF(632,1) .
