HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 185, 505, 80 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 185, 505, 80 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 185, 505, 80 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 185, 505, 80 is 5.
HCF(185, 505, 80) = 5
HCF of 185, 505, 80 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 185, 505, 80 is 5.
Highest Common Factor of 185,505,80 is 5
Step 1: Since 505 > 185, we apply the division lemma to 505 and 185, to get
505 = 185 x 2 + 135
Step 2: Since the reminder 185 ≠ 0, we apply division lemma to 135 and 185, to get
185 = 135 x 1 + 50
Step 3: We consider the new divisor 135 and the new remainder 50, and apply the division lemma to get
135 = 50 x 2 + 35
We consider the new divisor 50 and the new remainder 35,and apply the division lemma to get
50 = 35 x 1 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 185 and 505 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(50,35) = HCF(135,50) = HCF(185,135) = HCF(505,185) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 5, we apply the division lemma to 80 and 5, to get
80 = 5 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 80 is 5
Notice that 5 = HCF(80,5) .
