HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 638, 246, 50, 877 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 638, 246, 50, 877 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 638, 246, 50, 877 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 638, 246, 50, 877 is 1.
HCF(638, 246, 50, 877) = 1
HCF of 638, 246, 50, 877 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 638, 246, 50, 877 is 1.
Highest Common Factor of 638,246,50,877 is 1
Step 1: Since 638 > 246, we apply the division lemma to 638 and 246, to get
638 = 246 x 2 + 146
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 146 and 246, to get
246 = 146 x 1 + 100
Step 3: We consider the new divisor 146 and the new remainder 100, and apply the division lemma to get
146 = 100 x 1 + 46
We consider the new divisor 100 and the new remainder 46,and apply the division lemma to get
100 = 46 x 2 + 8
We consider the new divisor 46 and the new remainder 8,and apply the division lemma to get
46 = 8 x 5 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
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 638 and 246 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(46,8) = HCF(100,46) = HCF(146,100) = HCF(246,146) = HCF(638,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 2, we apply the division lemma to 50 and 2, to get
50 = 2 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 50 is 2
Notice that 2 = HCF(50,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 877 > 2, we apply the division lemma to 877 and 2, to get
877 = 2 x 438 + 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 877 is 1
Notice that 1 = HCF(2,1) = HCF(877,2) .
