HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 838, 46 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 838, 46 is 2 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, 838, 46 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, 838, 46 is 2.
HCF(986, 838, 46) = 2
HCF of 986, 838, 46 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, 838, 46 is 2.
Highest Common Factor of 986,838,46 is 2
Step 1: Since 986 > 838, we apply the division lemma to 986 and 838, to get
986 = 838 x 1 + 148
Step 2: Since the reminder 838 ≠ 0, we apply division lemma to 148 and 838, to get
838 = 148 x 5 + 98
Step 3: We consider the new divisor 148 and the new remainder 98, and apply the division lemma to get
148 = 98 x 1 + 50
We consider the new divisor 98 and the new remainder 50,and apply the division lemma to get
98 = 50 x 1 + 48
We consider the new divisor 50 and the new remainder 48,and apply the division lemma to get
50 = 48 x 1 + 2
We consider the new divisor 48 and the new remainder 2,and apply the division lemma to get
48 = 2 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 838 is 2
Notice that 2 = HCF(48,2) = HCF(50,48) = HCF(98,50) = HCF(148,98) = HCF(838,148) = HCF(986,838) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 2, we apply the division lemma to 46 and 2, to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 46 is 2
Notice that 2 = HCF(46,2) .
