HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 197, 647, 844 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 77, 197, 647, 844 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 77, 197, 647, 844 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 77, 197, 647, 844 is 1.
HCF(77, 197, 647, 844) = 1
HCF of 77, 197, 647, 844 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 77, 197, 647, 844 is 1.
Highest Common Factor of 77,197,647,844 is 1
Step 1: Since 197 > 77, we apply the division lemma to 197 and 77, to get
197 = 77 x 2 + 43
Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 43 and 77, to get
77 = 43 x 1 + 34
Step 3: We consider the new divisor 43 and the new remainder 34, and apply the division lemma to get
43 = 34 x 1 + 9
We consider the new divisor 34 and the new remainder 9,and apply the division lemma to get
34 = 9 x 3 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 77 and 197 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(34,9) = HCF(43,34) = HCF(77,43) = HCF(197,77) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 844 > 1, we apply the division lemma to 844 and 1, to get
844 = 1 x 844 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 844 is 1
Notice that 1 = HCF(844,1) .
