HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 382, 510, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 382, 510, 91 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 382, 510, 91 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 382, 510, 91 is 1.
HCF(382, 510, 91) = 1
HCF of 382, 510, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 382, 510, 91 is 1.
Highest Common Factor of 382,510,91 is 1
Step 1: Since 510 > 382, we apply the division lemma to 510 and 382, to get
510 = 382 x 1 + 128
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 128 and 382, to get
382 = 128 x 2 + 126
Step 3: We consider the new divisor 128 and the new remainder 126, and apply the division lemma to get
128 = 126 x 1 + 2
We consider the new divisor 126 and the new remainder 2, and apply the division lemma to get
126 = 2 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 382 and 510 is 2
Notice that 2 = HCF(126,2) = HCF(128,126) = HCF(382,128) = HCF(510,382) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 2, we apply the division lemma to 91 and 2, to get
91 = 2 x 45 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 91 is 1
Notice that 1 = HCF(2,1) = HCF(91,2) .
