HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 286, 476, 129 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 286, 476, 129 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 286, 476, 129 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 286, 476, 129 is 1.
HCF(286, 476, 129) = 1
HCF of 286, 476, 129 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 286, 476, 129 is 1.
Highest Common Factor of 286,476,129 is 1
Step 1: Since 476 > 286, we apply the division lemma to 476 and 286, to get
476 = 286 x 1 + 190
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 190 and 286, to get
286 = 190 x 1 + 96
Step 3: We consider the new divisor 190 and the new remainder 96, and apply the division lemma to get
190 = 96 x 1 + 94
We consider the new divisor 96 and the new remainder 94,and apply the division lemma to get
96 = 94 x 1 + 2
We consider the new divisor 94 and the new remainder 2,and apply the division lemma to get
94 = 2 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 286 and 476 is 2
Notice that 2 = HCF(94,2) = HCF(96,94) = HCF(190,96) = HCF(286,190) = HCF(476,286) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 129 > 2, we apply the division lemma to 129 and 2, to get
129 = 2 x 64 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 129 is 1
Notice that 1 = HCF(2,1) = HCF(129,2) .
