HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 646, 208, 92 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 646, 208, 92 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 402, 646, 208, 92 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 402, 646, 208, 92 is 2.
HCF(402, 646, 208, 92) = 2
HCF of 402, 646, 208, 92 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 402, 646, 208, 92 is 2.
Highest Common Factor of 402,646,208,92 is 2
Step 1: Since 646 > 402, we apply the division lemma to 646 and 402, to get
646 = 402 x 1 + 244
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 244 and 402, to get
402 = 244 x 1 + 158
Step 3: We consider the new divisor 244 and the new remainder 158, and apply the division lemma to get
244 = 158 x 1 + 86
We consider the new divisor 158 and the new remainder 86,and apply the division lemma to get
158 = 86 x 1 + 72
We consider the new divisor 86 and the new remainder 72,and apply the division lemma to get
86 = 72 x 1 + 14
We consider the new divisor 72 and the new remainder 14,and apply the division lemma to get
72 = 14 x 5 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 402 and 646 is 2
Notice that 2 = HCF(14,2) = HCF(72,14) = HCF(86,72) = HCF(158,86) = HCF(244,158) = HCF(402,244) = HCF(646,402) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 208 > 2, we apply the division lemma to 208 and 2, to get
208 = 2 x 104 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 208 is 2
Notice that 2 = HCF(208,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 92 > 2, we apply the division lemma to 92 and 2, to get
92 = 2 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 92 is 2
Notice that 2 = HCF(92,2) .
