HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 300 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 643, 300 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 643, 300 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 643, 300 is 1.
HCF(643, 300) = 1
HCF of 643, 300 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 643, 300 is 1.
Highest Common Factor of 643,300 is 1
Step 1: Since 643 > 300, we apply the division lemma to 643 and 300, to get
643 = 300 x 2 + 43
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 43 and 300, to get
300 = 43 x 6 + 42
Step 3: We consider the new divisor 43 and the new remainder 42, and apply the division lemma to get
43 = 42 x 1 + 1
We consider the new divisor 42 and the new remainder 1, and apply the division lemma to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 643 and 300 is 1
Notice that 1 = HCF(42,1) = HCF(43,42) = HCF(300,43) = HCF(643,300) .
