HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 192, 70 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 192, 70 is 2 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 192, 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 192, 70 is 2.
HCF(192, 70) = 2
HCF of 192, 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 192, 70 is 2.
Highest Common Factor of 192,70 is 2
Step 1: Since 192 > 70, we apply the division lemma to 192 and 70, to get
192 = 70 x 2 + 52
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 52 and 70, to get
70 = 52 x 1 + 18
Step 3: We consider the new divisor 52 and the new remainder 18, and apply the division lemma to get
52 = 18 x 2 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 192 and 70 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(52,18) = HCF(70,52) = HCF(192,70) .
