HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 668, 393 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, 393 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, 393 is 1.
HCF(668, 393) = 1
HCF of 668, 393 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, 393 is 1.
Highest Common Factor of 668,393 is 1
Step 1: Since 668 > 393, we apply the division lemma to 668 and 393, to get
668 = 393 x 1 + 275
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 275 and 393, to get
393 = 275 x 1 + 118
Step 3: We consider the new divisor 275 and the new remainder 118, and apply the division lemma to get
275 = 118 x 2 + 39
We consider the new divisor 118 and the new remainder 39,and apply the division lemma to get
118 = 39 x 3 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 668 and 393 is 1
Notice that 1 = HCF(39,1) = HCF(118,39) = HCF(275,118) = HCF(393,275) = HCF(668,393) .
