HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 246, 146 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 246, 146 is 2 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, 246, 146 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, 246, 146 is 2.
HCF(378, 246, 146) = 2
HCF of 378, 246, 146 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, 246, 146 is 2.
Highest Common Factor of 378,246,146 is 2
Step 1: Since 378 > 246, we apply the division lemma to 378 and 246, to get
378 = 246 x 1 + 132
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 132 and 246, to get
246 = 132 x 1 + 114
Step 3: We consider the new divisor 132 and the new remainder 114, and apply the division lemma to get
132 = 114 x 1 + 18
We consider the new divisor 114 and the new remainder 18,and apply the division lemma to get
114 = 18 x 6 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 378 and 246 is 6
Notice that 6 = HCF(18,6) = HCF(114,18) = HCF(132,114) = HCF(246,132) = HCF(378,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 6, we apply the division lemma to 146 and 6, to get
146 = 6 x 24 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 146 is 2
Notice that 2 = HCF(6,2) = HCF(146,6) .
