HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 413, 936 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 413, 936 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 981, 413, 936 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 981, 413, 936 is 1.
HCF(981, 413, 936) = 1
HCF of 981, 413, 936 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 413, 936 is 1.
Highest Common Factor of 981,413,936 is 1
Step 1: Since 981 > 413, we apply the division lemma to 981 and 413, to get
981 = 413 x 2 + 155
Step 2: Since the reminder 413 ≠ 0, we apply division lemma to 155 and 413, to get
413 = 155 x 2 + 103
Step 3: We consider the new divisor 155 and the new remainder 103, and apply the division lemma to get
155 = 103 x 1 + 52
We consider the new divisor 103 and the new remainder 52,and apply the division lemma to get
103 = 52 x 1 + 51
We consider the new divisor 52 and the new remainder 51,and apply the division lemma to get
52 = 51 x 1 + 1
We consider the new divisor 51 and the new remainder 1,and apply the division lemma to get
51 = 1 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 981 and 413 is 1
Notice that 1 = HCF(51,1) = HCF(52,51) = HCF(103,52) = HCF(155,103) = HCF(413,155) = HCF(981,413) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 936 > 1, we apply the division lemma to 936 and 1, to get
936 = 1 x 936 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 936 is 1
Notice that 1 = HCF(936,1) .
