HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1986, 254 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 1986, 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 1986, 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 1986, 254 is 2.
HCF(1986, 254) = 2
HCF of 1986, 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 1986, 254 is 2.
Highest Common Factor of 1986,254 is 2
Step 1: Since 1986 > 254, we apply the division lemma to 1986 and 254, to get
1986 = 254 x 7 + 208
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 208 and 254, to get
254 = 208 x 1 + 46
Step 3: We consider the new divisor 208 and the new remainder 46, and apply the division lemma to get
208 = 46 x 4 + 24
We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get
46 = 24 x 1 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1986 and 254 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(208,46) = HCF(254,208) = HCF(1986,254) .
