HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 33, 90 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 33, 90 is 3 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 33, 90 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 33, 90 is 3.
HCF(33, 90) = 3
HCF of 33, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 33, 90 is 3.
Highest Common Factor of 33,90 is 3
Step 1: Since 90 > 33, we apply the division lemma to 90 and 33, to get
90 = 33 x 2 + 24
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 24 and 33, to get
33 = 24 x 1 + 9
Step 3: We consider the new divisor 24 and the new remainder 9, and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 33 and 90 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(33,24) = HCF(90,33) .
