HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 71042 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 71042 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 639, 71042 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, 71042 is 1.
HCF(639, 71042) = 1
HCF of 639, 71042 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, 71042 is 1.
Highest Common Factor of 639,71042 is 1
Step 1: Since 71042 > 639, we apply the division lemma to 71042 and 639, to get
71042 = 639 x 111 + 113
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 113 and 639, to get
639 = 113 x 5 + 74
Step 3: We consider the new divisor 113 and the new remainder 74, and apply the division lemma to get
113 = 74 x 1 + 39
We consider the new divisor 74 and the new remainder 39,and apply the division lemma to get
74 = 39 x 1 + 35
We consider the new divisor 39 and the new remainder 35,and apply the division lemma to get
39 = 35 x 1 + 4
We consider the new divisor 35 and the new remainder 4,and apply the division lemma to get
35 = 4 x 8 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 71042 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(35,4) = HCF(39,35) = HCF(74,39) = HCF(113,74) = HCF(639,113) = HCF(71042,639) .
