HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 303, 195, 398, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 303, 195, 398, 169 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 303, 195, 398, 169 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 303, 195, 398, 169 is 1.
HCF(303, 195, 398, 169) = 1
HCF of 303, 195, 398, 169 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 303, 195, 398, 169 is 1.
Highest Common Factor of 303,195,398,169 is 1
Step 1: Since 303 > 195, we apply the division lemma to 303 and 195, to get
303 = 195 x 1 + 108
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 108 and 195, to get
195 = 108 x 1 + 87
Step 3: We consider the new divisor 108 and the new remainder 87, and apply the division lemma to get
108 = 87 x 1 + 21
We consider the new divisor 87 and the new remainder 21,and apply the division lemma to get
87 = 21 x 4 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 303 and 195 is 3
Notice that 3 = HCF(21,3) = HCF(87,21) = HCF(108,87) = HCF(195,108) = HCF(303,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 3, we apply the division lemma to 398 and 3, to get
398 = 3 x 132 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 398 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(398,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 169 > 1, we apply the division lemma to 169 and 1, to get
169 = 1 x 169 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 169 is 1
Notice that 1 = HCF(169,1) .
