HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 182, 840, 20 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 182, 840, 20 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 182, 840, 20 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 182, 840, 20 is 2.
HCF(182, 840, 20) = 2
HCF of 182, 840, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 182, 840, 20 is 2.
Highest Common Factor of 182,840,20 is 2
Step 1: Since 840 > 182, we apply the division lemma to 840 and 182, to get
840 = 182 x 4 + 112
Step 2: Since the reminder 182 ≠ 0, we apply division lemma to 112 and 182, to get
182 = 112 x 1 + 70
Step 3: We consider the new divisor 112 and the new remainder 70, and apply the division lemma to get
112 = 70 x 1 + 42
We consider the new divisor 70 and the new remainder 42,and apply the division lemma to get
70 = 42 x 1 + 28
We consider the new divisor 42 and the new remainder 28,and apply the division lemma to get
42 = 28 x 1 + 14
We consider the new divisor 28 and the new remainder 14,and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 182 and 840 is 14
Notice that 14 = HCF(28,14) = HCF(42,28) = HCF(70,42) = HCF(112,70) = HCF(182,112) = HCF(840,182) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 14, we apply the division lemma to 20 and 14, to get
20 = 14 x 1 + 6
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 6 and 14, to get
14 = 6 x 2 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 20 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) .
