HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 842, 604, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 298, 842, 604, 63 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 298, 842, 604, 63 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 298, 842, 604, 63 is 1.
HCF(298, 842, 604, 63) = 1
HCF of 298, 842, 604, 63 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 298, 842, 604, 63 is 1.
Highest Common Factor of 298,842,604,63 is 1
Step 1: Since 842 > 298, we apply the division lemma to 842 and 298, to get
842 = 298 x 2 + 246
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 246 and 298, to get
298 = 246 x 1 + 52
Step 3: We consider the new divisor 246 and the new remainder 52, and apply the division lemma to get
246 = 52 x 4 + 38
We consider the new divisor 52 and the new remainder 38,and apply the division lemma to get
52 = 38 x 1 + 14
We consider the new divisor 38 and the new remainder 14,and apply the division lemma to get
38 = 14 x 2 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 298 and 842 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(38,14) = HCF(52,38) = HCF(246,52) = HCF(298,246) = HCF(842,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 604 > 2, we apply the division lemma to 604 and 2, to get
604 = 2 x 302 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 604 is 2
Notice that 2 = HCF(604,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63 > 2, we apply the division lemma to 63 and 2, to get
63 = 2 x 31 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 63 is 1
Notice that 1 = HCF(2,1) = HCF(63,2) .
