HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 171, 556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 171, 556 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 653, 171, 556 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 653, 171, 556 is 1.
HCF(653, 171, 556) = 1
HCF of 653, 171, 556 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 171, 556 is 1.
Highest Common Factor of 653,171,556 is 1
Step 1: Since 653 > 171, we apply the division lemma to 653 and 171, to get
653 = 171 x 3 + 140
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 140 and 171, to get
171 = 140 x 1 + 31
Step 3: We consider the new divisor 140 and the new remainder 31, and apply the division lemma to get
140 = 31 x 4 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 171 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(140,31) = HCF(171,140) = HCF(653,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 556 > 1, we apply the division lemma to 556 and 1, to get
556 = 1 x 556 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 556 is 1
Notice that 1 = HCF(556,1) .
