HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 4629 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 4629 is 3 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 639, 4629 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 639, 4629 is 3.
HCF(639, 4629) = 3
HCF of 639, 4629 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 4629 is 3.
Highest Common Factor of 639,4629 is 3
Step 1: Since 4629 > 639, we apply the division lemma to 4629 and 639, to get
4629 = 639 x 7 + 156
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 156 and 639, to get
639 = 156 x 4 + 15
Step 3: We consider the new divisor 156 and the new remainder 15, and apply the division lemma to get
156 = 15 x 10 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 639 and 4629 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(156,15) = HCF(639,156) = HCF(4629,639) .
