HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 787, 56 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 324, 787, 56 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 324, 787, 56 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 324, 787, 56 is 1.
HCF(324, 787, 56) = 1
HCF of 324, 787, 56 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 324, 787, 56 is 1.
Highest Common Factor of 324,787,56 is 1
Step 1: Since 787 > 324, we apply the division lemma to 787 and 324, to get
787 = 324 x 2 + 139
Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 139 and 324, to get
324 = 139 x 2 + 46
Step 3: We consider the new divisor 139 and the new remainder 46, and apply the division lemma to get
139 = 46 x 3 + 1
We consider the new divisor 46 and the new remainder 1, and apply the division lemma to get
46 = 1 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 324 and 787 is 1
Notice that 1 = HCF(46,1) = HCF(139,46) = HCF(324,139) = HCF(787,324) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 56 > 1, we apply the division lemma to 56 and 1, to get
56 = 1 x 56 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 56 is 1
Notice that 1 = HCF(56,1) .
