HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 156, 336, 111 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 681, 156, 336, 111 is 3 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 681, 156, 336, 111 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 681, 156, 336, 111 is 3.
HCF(681, 156, 336, 111) = 3
HCF of 681, 156, 336, 111 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 681, 156, 336, 111 is 3.
Highest Common Factor of 681,156,336,111 is 3
Step 1: Since 681 > 156, we apply the division lemma to 681 and 156, to get
681 = 156 x 4 + 57
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 57 and 156, to get
156 = 57 x 2 + 42
Step 3: We consider the new divisor 57 and the new remainder 42, and apply the division lemma to get
57 = 42 x 1 + 15
We consider the new divisor 42 and the new remainder 15,and apply the division lemma to get
42 = 15 x 2 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 681 and 156 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(57,42) = HCF(156,57) = HCF(681,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 336 > 3, we apply the division lemma to 336 and 3, to get
336 = 3 x 112 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 336 is 3
Notice that 3 = HCF(336,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 111 > 3, we apply the division lemma to 111 and 3, to get
111 = 3 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 111 is 3
Notice that 3 = HCF(111,3) .
