HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 35, 420, 336 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 35, 420, 336 is 7 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 35, 420, 336 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 35, 420, 336 is 7.
HCF(35, 420, 336) = 7
HCF of 35, 420, 336 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 35, 420, 336 is 7.
Highest Common Factor of 35,420,336 is 7
Step 1: Since 420 > 35, we apply the division lemma to 420 and 35, to get
420 = 35 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 35 and 420 is 35
Notice that 35 = HCF(420,35) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 336 > 35, we apply the division lemma to 336 and 35, to get
336 = 35 x 9 + 21
Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 21 and 35, to get
35 = 21 x 1 + 14
Step 3: We consider the new divisor 21 and the new remainder 14, and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7, and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 35 and 336 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(336,35) .
