HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 842, 210, 200, 773 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 842, 210, 200, 773 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 842, 210, 200, 773 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 842, 210, 200, 773 is 1.
HCF(842, 210, 200, 773) = 1
HCF of 842, 210, 200, 773 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 842, 210, 200, 773 is 1.
Highest Common Factor of 842,210,200,773 is 1
Step 1: Since 842 > 210, we apply the division lemma to 842 and 210, to get
842 = 210 x 4 + 2
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 2 and 210, to get
210 = 2 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 842 and 210 is 2
Notice that 2 = HCF(210,2) = HCF(842,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 200 > 2, we apply the division lemma to 200 and 2, to get
200 = 2 x 100 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 200 is 2
Notice that 2 = HCF(200,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 773 > 2, we apply the division lemma to 773 and 2, to get
773 = 2 x 386 + 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 773 is 1
Notice that 1 = HCF(2,1) = HCF(773,2) .
