HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 986, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 442, 986, 659 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 442, 986, 659 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 442, 986, 659 is 1.
HCF(442, 986, 659) = 1
HCF of 442, 986, 659 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 442, 986, 659 is 1.
Highest Common Factor of 442,986,659 is 1
Step 1: Since 986 > 442, we apply the division lemma to 986 and 442, to get
986 = 442 x 2 + 102
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 102 and 442, to get
442 = 102 x 4 + 34
Step 3: We consider the new divisor 102 and the new remainder 34, and apply the division lemma to get
102 = 34 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 442 and 986 is 34
Notice that 34 = HCF(102,34) = HCF(442,102) = HCF(986,442) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 659 > 34, we apply the division lemma to 659 and 34, to get
659 = 34 x 19 + 13
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 13 and 34, to get
34 = 13 x 2 + 8
Step 3: We consider the new divisor 13 and the new remainder 8, and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 34 and 659 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(659,34) .
