HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 256, 510 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 256, 510 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 651, 256, 510 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 651, 256, 510 is 1.
HCF(651, 256, 510) = 1
HCF of 651, 256, 510 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 256, 510 is 1.
Highest Common Factor of 651,256,510 is 1
Step 1: Since 651 > 256, we apply the division lemma to 651 and 256, to get
651 = 256 x 2 + 139
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 139 and 256, to get
256 = 139 x 1 + 117
Step 3: We consider the new divisor 139 and the new remainder 117, and apply the division lemma to get
139 = 117 x 1 + 22
We consider the new divisor 117 and the new remainder 22,and apply the division lemma to get
117 = 22 x 5 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 256 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(117,22) = HCF(139,117) = HCF(256,139) = HCF(651,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 510 > 1, we apply the division lemma to 510 and 1, to get
510 = 1 x 510 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 510 is 1
Notice that 1 = HCF(510,1) .
