HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 33, 88, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 33, 88, 70 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 33, 88, 70 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, 88, 70 is 1.
HCF(33, 88, 70) = 1
HCF of 33, 88, 70 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, 88, 70 is 1.
Highest Common Factor of 33,88,70 is 1
Step 1: Since 88 > 33, we apply the division lemma to 88 and 33, to get
88 = 33 x 2 + 22
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 22 and 33, to get
33 = 22 x 1 + 11
Step 3: We consider the new divisor 22 and the new remainder 11, and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 33 and 88 is 11
Notice that 11 = HCF(22,11) = HCF(33,22) = HCF(88,33) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 11, we apply the division lemma to 70 and 11, to get
70 = 11 x 6 + 4
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 4 and 11, to get
11 = 4 x 2 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 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 11 and 70 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(70,11) .
