HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 368, 947, 168 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 368, 947, 168 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 368, 947, 168 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 368, 947, 168 is 1.
HCF(368, 947, 168) = 1
HCF of 368, 947, 168 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 368, 947, 168 is 1.
Highest Common Factor of 368,947,168 is 1
Step 1: Since 947 > 368, we apply the division lemma to 947 and 368, to get
947 = 368 x 2 + 211
Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 211 and 368, to get
368 = 211 x 1 + 157
Step 3: We consider the new divisor 211 and the new remainder 157, and apply the division lemma to get
211 = 157 x 1 + 54
We consider the new divisor 157 and the new remainder 54,and apply the division lemma to get
157 = 54 x 2 + 49
We consider the new divisor 54 and the new remainder 49,and apply the division lemma to get
54 = 49 x 1 + 5
We consider the new divisor 49 and the new remainder 5,and apply the division lemma to get
49 = 5 x 9 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 368 and 947 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(49,5) = HCF(54,49) = HCF(157,54) = HCF(211,157) = HCF(368,211) = HCF(947,368) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 1, we apply the division lemma to 168 and 1, to get
168 = 1 x 168 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 168 is 1
Notice that 1 = HCF(168,1) .
