HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 678, 263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 678, 263 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 986, 678, 263 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 986, 678, 263 is 1.
HCF(986, 678, 263) = 1
HCF of 986, 678, 263 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 678, 263 is 1.
Highest Common Factor of 986,678,263 is 1
Step 1: Since 986 > 678, we apply the division lemma to 986 and 678, to get
986 = 678 x 1 + 308
Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 308 and 678, to get
678 = 308 x 2 + 62
Step 3: We consider the new divisor 308 and the new remainder 62, and apply the division lemma to get
308 = 62 x 4 + 60
We consider the new divisor 62 and the new remainder 60,and apply the division lemma to get
62 = 60 x 1 + 2
We consider the new divisor 60 and the new remainder 2,and apply the division lemma to get
60 = 2 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 678 is 2
Notice that 2 = HCF(60,2) = HCF(62,60) = HCF(308,62) = HCF(678,308) = HCF(986,678) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 263 > 2, we apply the division lemma to 263 and 2, to get
263 = 2 x 131 + 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 263 is 1
Notice that 1 = HCF(2,1) = HCF(263,2) .
