HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 392, 171 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 392, 171 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 553, 392, 171 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 553, 392, 171 is 1.
HCF(553, 392, 171) = 1
HCF of 553, 392, 171 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 392, 171 is 1.
Highest Common Factor of 553,392,171 is 1
Step 1: Since 553 > 392, we apply the division lemma to 553 and 392, to get
553 = 392 x 1 + 161
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 161 and 392, to get
392 = 161 x 2 + 70
Step 3: We consider the new divisor 161 and the new remainder 70, and apply the division lemma to get
161 = 70 x 2 + 21
We consider the new divisor 70 and the new remainder 21,and apply the division lemma to get
70 = 21 x 3 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 553 and 392 is 7
Notice that 7 = HCF(21,7) = HCF(70,21) = HCF(161,70) = HCF(392,161) = HCF(553,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 171 > 7, we apply the division lemma to 171 and 7, to get
171 = 7 x 24 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: 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 7 and 171 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(171,7) .
