HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 620, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 620, 347 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, 620, 347 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, 620, 347 is 1.
HCF(986, 620, 347) = 1
HCF of 986, 620, 347 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, 620, 347 is 1.
Highest Common Factor of 986,620,347 is 1
Step 1: Since 986 > 620, we apply the division lemma to 986 and 620, to get
986 = 620 x 1 + 366
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 366 and 620, to get
620 = 366 x 1 + 254
Step 3: We consider the new divisor 366 and the new remainder 254, and apply the division lemma to get
366 = 254 x 1 + 112
We consider the new divisor 254 and the new remainder 112,and apply the division lemma to get
254 = 112 x 2 + 30
We consider the new divisor 112 and the new remainder 30,and apply the division lemma to get
112 = 30 x 3 + 22
We consider the new divisor 30 and the new remainder 22,and apply the division lemma to get
30 = 22 x 1 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 620 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(30,22) = HCF(112,30) = HCF(254,112) = HCF(366,254) = HCF(620,366) = HCF(986,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 347 > 2, we apply the division lemma to 347 and 2, to get
347 = 2 x 173 + 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 347 is 1
Notice that 1 = HCF(2,1) = HCF(347,2) .
