HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 388 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 388 is 2 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 494, 388 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 494, 388 is 2.
HCF(494, 388) = 2
HCF of 494, 388 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 388 is 2.
Highest Common Factor of 494,388 is 2
Step 1: Since 494 > 388, we apply the division lemma to 494 and 388, to get
494 = 388 x 1 + 106
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 106 and 388, to get
388 = 106 x 3 + 70
Step 3: We consider the new divisor 106 and the new remainder 70, and apply the division lemma to get
106 = 70 x 1 + 36
We consider the new divisor 70 and the new remainder 36,and apply the division lemma to get
70 = 36 x 1 + 34
We consider the new divisor 36 and the new remainder 34,and apply the division lemma to get
36 = 34 x 1 + 2
We consider the new divisor 34 and the new remainder 2,and apply the division lemma to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 494 and 388 is 2
Notice that 2 = HCF(34,2) = HCF(36,34) = HCF(70,36) = HCF(106,70) = HCF(388,106) = HCF(494,388) .
