HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 620 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 479, 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 479, 620 is 1.
HCF(479, 620) = 1
HCF of 479, 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 479, 620 is 1.
Highest Common Factor of 479,620 is 1
Step 1: Since 620 > 479, we apply the division lemma to 620 and 479, to get
620 = 479 x 1 + 141
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 141 and 479, to get
479 = 141 x 3 + 56
Step 3: We consider the new divisor 141 and the new remainder 56, and apply the division lemma to get
141 = 56 x 2 + 29
We consider the new divisor 56 and the new remainder 29,and apply the division lemma to get
56 = 29 x 1 + 27
We consider the new divisor 29 and the new remainder 27,and apply the division lemma to get
29 = 27 x 1 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 1
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 479 and 620 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(56,29) = HCF(141,56) = HCF(479,141) = HCF(620,479) .
