HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 733, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 733, 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 733, 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 733, 643 is 1.
HCF(733, 643) = 1
HCF of 733, 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 733, 643 is 1.
Highest Common Factor of 733,643 is 1
Step 1: Since 733 > 643, we apply the division lemma to 733 and 643, to get
733 = 643 x 1 + 90
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 90 and 643, to get
643 = 90 x 7 + 13
Step 3: We consider the new divisor 90 and the new remainder 13, and apply the division lemma to get
90 = 13 x 6 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 733 and 643 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(90,13) = HCF(643,90) = HCF(733,643) .
