HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 50, 388, 638 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 50, 388, 638 is 2 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 56, 50, 388, 638 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 56, 50, 388, 638 is 2.
HCF(56, 50, 388, 638) = 2
HCF of 56, 50, 388, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 56, 50, 388, 638 is 2.
Highest Common Factor of 56,50,388,638 is 2
Step 1: Since 56 > 50, we apply the division lemma to 56 and 50, to get
56 = 50 x 1 + 6
Step 2: Since the reminder 50 ≠ 0, we apply division lemma to 6 and 50, to get
50 = 6 x 8 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 56 and 50 is 2
Notice that 2 = HCF(6,2) = HCF(50,6) = HCF(56,50) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 388 > 2, we apply the division lemma to 388 and 2, to get
388 = 2 x 194 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 388 is 2
Notice that 2 = HCF(388,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 638 > 2, we apply the division lemma to 638 and 2, to get
638 = 2 x 319 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 638 is 2
Notice that 2 = HCF(638,2) .
