HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 6983 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 668, 6983 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 668, 6983 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 668, 6983 is 1.
HCF(668, 6983) = 1
HCF of 668, 6983 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 668, 6983 is 1.
Highest Common Factor of 668,6983 is 1
Step 1: Since 6983 > 668, we apply the division lemma to 6983 and 668, to get
6983 = 668 x 10 + 303
Step 2: Since the reminder 668 ≠ 0, we apply division lemma to 303 and 668, to get
668 = 303 x 2 + 62
Step 3: We consider the new divisor 303 and the new remainder 62, and apply the division lemma to get
303 = 62 x 4 + 55
We consider the new divisor 62 and the new remainder 55,and apply the division lemma to get
62 = 55 x 1 + 7
We consider the new divisor 55 and the new remainder 7,and apply the division lemma to get
55 = 7 x 7 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 668 and 6983 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(55,7) = HCF(62,55) = HCF(303,62) = HCF(668,303) = HCF(6983,668) .
