HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 518, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 518, 166 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 779, 518, 166 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 779, 518, 166 is 1.
HCF(779, 518, 166) = 1
HCF of 779, 518, 166 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 518, 166 is 1.
Highest Common Factor of 779,518,166 is 1
Step 1: Since 779 > 518, we apply the division lemma to 779 and 518, to get
779 = 518 x 1 + 261
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 261 and 518, to get
518 = 261 x 1 + 257
Step 3: We consider the new divisor 261 and the new remainder 257, and apply the division lemma to get
261 = 257 x 1 + 4
We consider the new divisor 257 and the new remainder 4,and apply the division lemma to get
257 = 4 x 64 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 518 is 1
Notice that 1 = HCF(4,1) = HCF(257,4) = HCF(261,257) = HCF(518,261) = HCF(779,518) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 166 > 1, we apply the division lemma to 166 and 1, to get
166 = 1 x 166 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 166 is 1
Notice that 1 = HCF(166,1) .
