HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 411, 238 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 411, 238 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 986, 411, 238 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 986, 411, 238 is 1.
HCF(986, 411, 238) = 1
HCF of 986, 411, 238 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 411, 238 is 1.
Highest Common Factor of 986,411,238 is 1
Step 1: Since 986 > 411, we apply the division lemma to 986 and 411, to get
986 = 411 x 2 + 164
Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 164 and 411, to get
411 = 164 x 2 + 83
Step 3: We consider the new divisor 164 and the new remainder 83, and apply the division lemma to get
164 = 83 x 1 + 81
We consider the new divisor 83 and the new remainder 81,and apply the division lemma to get
83 = 81 x 1 + 2
We consider the new divisor 81 and the new remainder 2,and apply the division lemma to get
81 = 2 x 40 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 986 and 411 is 1
Notice that 1 = HCF(2,1) = HCF(81,2) = HCF(83,81) = HCF(164,83) = HCF(411,164) = HCF(986,411) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 238 > 1, we apply the division lemma to 238 and 1, to get
238 = 1 x 238 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 238 is 1
Notice that 1 = HCF(238,1) .
