HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3757, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 3757, 643 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 3757, 643 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 3757, 643 is 1.
HCF(3757, 643) = 1
HCF of 3757, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3757, 643 is 1.
Highest Common Factor of 3757,643 is 1
Step 1: Since 3757 > 643, we apply the division lemma to 3757 and 643, to get
3757 = 643 x 5 + 542
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 542 and 643, to get
643 = 542 x 1 + 101
Step 3: We consider the new divisor 542 and the new remainder 101, and apply the division lemma to get
542 = 101 x 5 + 37
We consider the new divisor 101 and the new remainder 37,and apply the division lemma to get
101 = 37 x 2 + 27
We consider the new divisor 37 and the new remainder 27,and apply the division lemma to get
37 = 27 x 1 + 10
We consider the new divisor 27 and the new remainder 10,and apply the division lemma to get
27 = 10 x 2 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 3757 and 643 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(27,10) = HCF(37,27) = HCF(101,37) = HCF(542,101) = HCF(643,542) = HCF(3757,643) .
