HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 173, 981, 505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 173, 981, 505 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 173, 981, 505 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 173, 981, 505 is 1.
HCF(173, 981, 505) = 1
HCF of 173, 981, 505 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 173, 981, 505 is 1.
Highest Common Factor of 173,981,505 is 1
Step 1: Since 981 > 173, we apply the division lemma to 981 and 173, to get
981 = 173 x 5 + 116
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 116 and 173, to get
173 = 116 x 1 + 57
Step 3: We consider the new divisor 116 and the new remainder 57, and apply the division lemma to get
116 = 57 x 2 + 2
We consider the new divisor 57 and the new remainder 2,and apply the division lemma to get
57 = 2 x 28 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 173 and 981 is 1
Notice that 1 = HCF(2,1) = HCF(57,2) = HCF(116,57) = HCF(173,116) = HCF(981,173) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
