HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 945, 934 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 945, 934 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 378, 945, 934 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 378, 945, 934 is 1.
HCF(378, 945, 934) = 1
HCF of 378, 945, 934 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 945, 934 is 1.
Highest Common Factor of 378,945,934 is 1
Step 1: Since 945 > 378, we apply the division lemma to 945 and 378, to get
945 = 378 x 2 + 189
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 189 and 378, to get
378 = 189 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 189, the HCF of 378 and 945 is 189
Notice that 189 = HCF(378,189) = HCF(945,378) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 934 > 189, we apply the division lemma to 934 and 189, to get
934 = 189 x 4 + 178
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 178 and 189, to get
189 = 178 x 1 + 11
Step 3: We consider the new divisor 178 and the new remainder 11, and apply the division lemma to get
178 = 11 x 16 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 189 and 934 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(178,11) = HCF(189,178) = HCF(934,189) .
