HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 51, 784, 124 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 12, 51, 784, 124 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 12, 51, 784, 124 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 12, 51, 784, 124 is 1.
HCF(12, 51, 784, 124) = 1
HCF of 12, 51, 784, 124 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 12, 51, 784, 124 is 1.
Highest Common Factor of 12,51,784,124 is 1
Step 1: Since 51 > 12, we apply the division lemma to 51 and 12, to get
51 = 12 x 4 + 3
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 3 and 12, to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 51 is 3
Notice that 3 = HCF(12,3) = HCF(51,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 784 > 3, we apply the division lemma to 784 and 3, to get
784 = 3 x 261 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 784 is 1
Notice that 1 = HCF(3,1) = HCF(784,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 124 > 1, we apply the division lemma to 124 and 1, to get
124 = 1 x 124 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 124 is 1
Notice that 1 = HCF(124,1) .
