HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 182, 676, 620 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 182, 676, 620 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, 676, 620 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, 676, 620 is 2.
HCF(182, 676, 620) = 2
HCF of 182, 676, 620 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, 676, 620 is 2.
Highest Common Factor of 182,676,620 is 2
Step 1: Since 676 > 182, we apply the division lemma to 676 and 182, to get
676 = 182 x 3 + 130
Step 2: Since the reminder 182 ≠ 0, we apply division lemma to 130 and 182, to get
182 = 130 x 1 + 52
Step 3: We consider the new divisor 130 and the new remainder 52, and apply the division lemma to get
130 = 52 x 2 + 26
We consider the new divisor 52 and the new remainder 26, and apply the division lemma to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 182 and 676 is 26
Notice that 26 = HCF(52,26) = HCF(130,52) = HCF(182,130) = HCF(676,182) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 26, we apply the division lemma to 620 and 26, to get
620 = 26 x 23 + 22
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 22 and 26, to get
26 = 22 x 1 + 4
Step 3: We consider the new divisor 22 and the new remainder 4, and apply the division lemma to get
22 = 4 x 5 + 2
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 26 and 620 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(620,26) .
