HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 846, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 846, 763 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 647, 846, 763 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 647, 846, 763 is 1.
HCF(647, 846, 763) = 1
HCF of 647, 846, 763 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 846, 763 is 1.
Highest Common Factor of 647,846,763 is 1
Step 1: Since 846 > 647, we apply the division lemma to 846 and 647, to get
846 = 647 x 1 + 199
Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 199 and 647, to get
647 = 199 x 3 + 50
Step 3: We consider the new divisor 199 and the new remainder 50, and apply the division lemma to get
199 = 50 x 3 + 49
We consider the new divisor 50 and the new remainder 49,and apply the division lemma to get
50 = 49 x 1 + 1
We consider the new divisor 49 and the new remainder 1,and apply the division lemma to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 647 and 846 is 1
Notice that 1 = HCF(49,1) = HCF(50,49) = HCF(199,50) = HCF(647,199) = HCF(846,647) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 763 > 1, we apply the division lemma to 763 and 1, to get
763 = 1 x 763 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 763 is 1
Notice that 1 = HCF(763,1) .
