HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 662, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 662, 629 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 620, 662, 629 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 620, 662, 629 is 1.
HCF(620, 662, 629) = 1
HCF of 620, 662, 629 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 662, 629 is 1.
Highest Common Factor of 620,662,629 is 1
Step 1: Since 662 > 620, we apply the division lemma to 662 and 620, to get
662 = 620 x 1 + 42
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 42 and 620, to get
620 = 42 x 14 + 32
Step 3: We consider the new divisor 42 and the new remainder 32, and apply the division lemma to get
42 = 32 x 1 + 10
We consider the new divisor 32 and the new remainder 10,and apply the division lemma to get
32 = 10 x 3 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 662 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) = HCF(42,32) = HCF(620,42) = HCF(662,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 629 > 2, we apply the division lemma to 629 and 2, to get
629 = 2 x 314 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 629 is 1
Notice that 1 = HCF(2,1) = HCF(629,2) .
