HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 195, 262 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 195, 262 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 390, 195, 262 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 390, 195, 262 is 1.
HCF(390, 195, 262) = 1
HCF of 390, 195, 262 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 195, 262 is 1.
Highest Common Factor of 390,195,262 is 1
Step 1: Since 390 > 195, we apply the division lemma to 390 and 195, to get
390 = 195 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 195, the HCF of 390 and 195 is 195
Notice that 195 = HCF(390,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 262 > 195, we apply the division lemma to 262 and 195, to get
262 = 195 x 1 + 67
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 67 and 195, to get
195 = 67 x 2 + 61
Step 3: We consider the new divisor 67 and the new remainder 61, and apply the division lemma to get
67 = 61 x 1 + 6
We consider the new divisor 61 and the new remainder 6,and apply the division lemma to get
61 = 6 x 10 + 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 195 and 262 is 1
Notice that 1 = HCF(6,1) = HCF(61,6) = HCF(67,61) = HCF(195,67) = HCF(262,195) .
