HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 798, 642 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 228, 798, 642 is 6 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 228, 798, 642 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 228, 798, 642 is 6.
HCF(228, 798, 642) = 6
HCF of 228, 798, 642 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 228, 798, 642 is 6.
Highest Common Factor of 228,798,642 is 6
Step 1: Since 798 > 228, we apply the division lemma to 798 and 228, to get
798 = 228 x 3 + 114
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 114 and 228, to get
228 = 114 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 114, the HCF of 228 and 798 is 114
Notice that 114 = HCF(228,114) = HCF(798,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 642 > 114, we apply the division lemma to 642 and 114, to get
642 = 114 x 5 + 72
Step 2: Since the reminder 114 ≠ 0, we apply division lemma to 72 and 114, to get
114 = 72 x 1 + 42
Step 3: We consider the new divisor 72 and the new remainder 42, and apply the division lemma to get
72 = 42 x 1 + 30
We consider the new divisor 42 and the new remainder 30,and apply the division lemma to get
42 = 30 x 1 + 12
We consider the new divisor 30 and the new remainder 12,and apply the division lemma to get
30 = 12 x 2 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 114 and 642 is 6
Notice that 6 = HCF(12,6) = HCF(30,12) = HCF(42,30) = HCF(72,42) = HCF(114,72) = HCF(642,114) .
