HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 413, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 177, 413, 31 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 177, 413, 31 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 177, 413, 31 is 1.
HCF(177, 413, 31) = 1
HCF of 177, 413, 31 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 177, 413, 31 is 1.
Highest Common Factor of 177,413,31 is 1
Step 1: Since 413 > 177, we apply the division lemma to 413 and 177, to get
413 = 177 x 2 + 59
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 59 and 177, to get
177 = 59 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 59, the HCF of 177 and 413 is 59
Notice that 59 = HCF(177,59) = HCF(413,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 31, we apply the division lemma to 59 and 31, to get
59 = 31 x 1 + 28
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 28 and 31, to get
31 = 28 x 1 + 3
Step 3: We consider the new divisor 28 and the new remainder 3, and apply the division lemma to get
28 = 3 x 9 + 1
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 59 and 31 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(31,28) = HCF(59,31) .
