HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 946, 171, 938 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 946, 171, 938 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 946, 171, 938 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 946, 171, 938 is 1.
HCF(946, 171, 938) = 1
HCF of 946, 171, 938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 946, 171, 938 is 1.
Highest Common Factor of 946,171,938 is 1
Step 1: Since 946 > 171, we apply the division lemma to 946 and 171, to get
946 = 171 x 5 + 91
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 91 and 171, to get
171 = 91 x 1 + 80
Step 3: We consider the new divisor 91 and the new remainder 80, and apply the division lemma to get
91 = 80 x 1 + 11
We consider the new divisor 80 and the new remainder 11,and apply the division lemma to get
80 = 11 x 7 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 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 946 and 171 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(80,11) = HCF(91,80) = HCF(171,91) = HCF(946,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 938 > 1, we apply the division lemma to 938 and 1, to get
938 = 1 x 938 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 938 is 1
Notice that 1 = HCF(938,1) .
