HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 860, 254 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 860, 254 is 2 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 68, 860, 254 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 68, 860, 254 is 2.
HCF(68, 860, 254) = 2
HCF of 68, 860, 254 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 860, 254 is 2.
Highest Common Factor of 68,860,254 is 2
Step 1: Since 860 > 68, we apply the division lemma to 860 and 68, to get
860 = 68 x 12 + 44
Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 44 and 68, to get
68 = 44 x 1 + 24
Step 3: We consider the new divisor 44 and the new remainder 24, and apply the division lemma to get
44 = 24 x 1 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 68 and 860 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(68,44) = HCF(860,68) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 254 > 4, we apply the division lemma to 254 and 4, to get
254 = 4 x 63 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 254 is 2
Notice that 2 = HCF(4,2) = HCF(254,4) .
