HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 874, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 177, 874, 781 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, 874, 781 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, 874, 781 is 1.
HCF(177, 874, 781) = 1
HCF of 177, 874, 781 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, 874, 781 is 1.
Highest Common Factor of 177,874,781 is 1
Step 1: Since 874 > 177, we apply the division lemma to 874 and 177, to get
874 = 177 x 4 + 166
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 166 and 177, to get
177 = 166 x 1 + 11
Step 3: We consider the new divisor 166 and the new remainder 11, and apply the division lemma to get
166 = 11 x 15 + 1
We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 177 and 874 is 1
Notice that 1 = HCF(11,1) = HCF(166,11) = HCF(177,166) = HCF(874,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get
781 = 1 x 781 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1
Notice that 1 = HCF(781,1) .
