HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 937 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 642, 937 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 642, 937 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 642, 937 is 1.
HCF(642, 937) = 1
HCF of 642, 937 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 642, 937 is 1.
Highest Common Factor of 642,937 is 1
Step 1: Since 937 > 642, we apply the division lemma to 937 and 642, to get
937 = 642 x 1 + 295
Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 295 and 642, to get
642 = 295 x 2 + 52
Step 3: We consider the new divisor 295 and the new remainder 52, and apply the division lemma to get
295 = 52 x 5 + 35
We consider the new divisor 52 and the new remainder 35,and apply the division lemma to get
52 = 35 x 1 + 17
We consider the new divisor 35 and the new remainder 17,and apply the division lemma to get
35 = 17 x 2 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 642 and 937 is 1
Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(52,35) = HCF(295,52) = HCF(642,295) = HCF(937,642) .
