HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 933, 665, 385 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 933, 665, 385 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 933, 665, 385 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 933, 665, 385 is 1.
HCF(933, 665, 385) = 1
HCF of 933, 665, 385 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 933, 665, 385 is 1.
Highest Common Factor of 933,665,385 is 1
Step 1: Since 933 > 665, we apply the division lemma to 933 and 665, to get
933 = 665 x 1 + 268
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 268 and 665, to get
665 = 268 x 2 + 129
Step 3: We consider the new divisor 268 and the new remainder 129, and apply the division lemma to get
268 = 129 x 2 + 10
We consider the new divisor 129 and the new remainder 10,and apply the division lemma to get
129 = 10 x 12 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 933 and 665 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(129,10) = HCF(268,129) = HCF(665,268) = HCF(933,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 385 > 1, we apply the division lemma to 385 and 1, to get
385 = 1 x 385 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 385 is 1
Notice that 1 = HCF(385,1) .
