HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 142, 994, 62 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 142, 994, 62 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 315, 142, 994, 62 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 315, 142, 994, 62 is 1.
HCF(315, 142, 994, 62) = 1
HCF of 315, 142, 994, 62 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 142, 994, 62 is 1.
Highest Common Factor of 315,142,994,62 is 1
Step 1: Since 315 > 142, we apply the division lemma to 315 and 142, to get
315 = 142 x 2 + 31
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 31 and 142, to get
142 = 31 x 4 + 18
Step 3: We consider the new divisor 31 and the new remainder 18, and apply the division lemma to get
31 = 18 x 1 + 13
We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get
18 = 13 x 1 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 315 and 142 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(142,31) = HCF(315,142) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 994 > 1, we apply the division lemma to 994 and 1, to get
994 = 1 x 994 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 994 is 1
Notice that 1 = HCF(994,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 62 > 1, we apply the division lemma to 62 and 1, to get
62 = 1 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 62 is 1
Notice that 1 = HCF(62,1) .
