HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 618, 52 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 618, 52 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 840, 618, 52 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 840, 618, 52 is 2.
HCF(840, 618, 52) = 2
HCF of 840, 618, 52 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 618, 52 is 2.
Highest Common Factor of 840,618,52 is 2
Step 1: Since 840 > 618, we apply the division lemma to 840 and 618, to get
840 = 618 x 1 + 222
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 222 and 618, to get
618 = 222 x 2 + 174
Step 3: We consider the new divisor 222 and the new remainder 174, and apply the division lemma to get
222 = 174 x 1 + 48
We consider the new divisor 174 and the new remainder 48,and apply the division lemma to get
174 = 48 x 3 + 30
We consider the new divisor 48 and the new remainder 30,and apply the division lemma to get
48 = 30 x 1 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 840 and 618 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(48,30) = HCF(174,48) = HCF(222,174) = HCF(618,222) = HCF(840,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 6, we apply the division lemma to 52 and 6, to get
52 = 6 x 8 + 4
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get
6 = 4 x 1 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 52 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(52,6) .
