HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 190, 265, 20 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 190, 265, 20 is 5 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 190, 265, 20 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 190, 265, 20 is 5.
HCF(190, 265, 20) = 5
HCF of 190, 265, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 190, 265, 20 is 5.
Highest Common Factor of 190,265,20 is 5
Step 1: Since 265 > 190, we apply the division lemma to 265 and 190, to get
265 = 190 x 1 + 75
Step 2: Since the reminder 190 ≠ 0, we apply division lemma to 75 and 190, to get
190 = 75 x 2 + 40
Step 3: We consider the new divisor 75 and the new remainder 40, and apply the division lemma to get
75 = 40 x 1 + 35
We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get
40 = 35 x 1 + 5
We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 190 and 265 is 5
Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(75,40) = HCF(190,75) = HCF(265,190) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 5, we apply the division lemma to 20 and 5, to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 20 is 5
Notice that 5 = HCF(20,5) .
