HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 368, 635, 50 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 218, 368, 635, 50 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 218, 368, 635, 50 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 218, 368, 635, 50 is 1.
HCF(218, 368, 635, 50) = 1
HCF of 218, 368, 635, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 218, 368, 635, 50 is 1.
Highest Common Factor of 218,368,635,50 is 1
Step 1: Since 368 > 218, we apply the division lemma to 368 and 218, to get
368 = 218 x 1 + 150
Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 150 and 218, to get
218 = 150 x 1 + 68
Step 3: We consider the new divisor 150 and the new remainder 68, and apply the division lemma to get
150 = 68 x 2 + 14
We consider the new divisor 68 and the new remainder 14,and apply the division lemma to get
68 = 14 x 4 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 218 and 368 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(68,14) = HCF(150,68) = HCF(218,150) = HCF(368,218) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 2, we apply the division lemma to 635 and 2, to get
635 = 2 x 317 + 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 635 is 1
Notice that 1 = HCF(2,1) = HCF(635,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 1, we apply the division lemma to 50 and 1, to get
50 = 1 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 50 is 1
Notice that 1 = HCF(50,1) .
