HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 972, 246 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 972, 246 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 338, 972, 246 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 338, 972, 246 is 2.
HCF(338, 972, 246) = 2
HCF of 338, 972, 246 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 972, 246 is 2.
Highest Common Factor of 338,972,246 is 2
Step 1: Since 972 > 338, we apply the division lemma to 972 and 338, to get
972 = 338 x 2 + 296
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 296 and 338, to get
338 = 296 x 1 + 42
Step 3: We consider the new divisor 296 and the new remainder 42, and apply the division lemma to get
296 = 42 x 7 + 2
We consider the new divisor 42 and the new remainder 2, and apply the division lemma to get
42 = 2 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 338 and 972 is 2
Notice that 2 = HCF(42,2) = HCF(296,42) = HCF(338,296) = HCF(972,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 246 > 2, we apply the division lemma to 246 and 2, to get
246 = 2 x 123 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 246 is 2
Notice that 2 = HCF(246,2) .
