HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 246, 399, 839 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 246, 399, 839 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 246, 399, 839 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 246, 399, 839 is 1.
HCF(246, 399, 839) = 1
HCF of 246, 399, 839 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 246, 399, 839 is 1.
Highest Common Factor of 246,399,839 is 1
Step 1: Since 399 > 246, we apply the division lemma to 399 and 246, to get
399 = 246 x 1 + 153
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 153 and 246, to get
246 = 153 x 1 + 93
Step 3: We consider the new divisor 153 and the new remainder 93, and apply the division lemma to get
153 = 93 x 1 + 60
We consider the new divisor 93 and the new remainder 60,and apply the division lemma to get
93 = 60 x 1 + 33
We consider the new divisor 60 and the new remainder 33,and apply the division lemma to get
60 = 33 x 1 + 27
We consider the new divisor 33 and the new remainder 27,and apply the division lemma to get
33 = 27 x 1 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 246 and 399 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(33,27) = HCF(60,33) = HCF(93,60) = HCF(153,93) = HCF(246,153) = HCF(399,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 839 > 3, we apply the division lemma to 839 and 3, to get
839 = 3 x 279 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 839 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(839,3) .
