HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 777, 587 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 777, 587 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, 777, 587 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, 777, 587 is 1.
HCF(647, 777, 587) = 1
HCF of 647, 777, 587 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, 777, 587 is 1.
Highest Common Factor of 647,777,587 is 1
Step 1: Since 777 > 647, we apply the division lemma to 777 and 647, to get
777 = 647 x 1 + 130
Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 130 and 647, to get
647 = 130 x 4 + 127
Step 3: We consider the new divisor 130 and the new remainder 127, and apply the division lemma to get
130 = 127 x 1 + 3
We consider the new divisor 127 and the new remainder 3,and apply the division lemma to get
127 = 3 x 42 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 647 and 777 is 1
Notice that 1 = HCF(3,1) = HCF(127,3) = HCF(130,127) = HCF(647,130) = HCF(777,647) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 587 > 1, we apply the division lemma to 587 and 1, to get
587 = 1 x 587 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 587 is 1
Notice that 1 = HCF(587,1) .
