HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 648, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 648, 251 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 977, 648, 251 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 977, 648, 251 is 1.
HCF(977, 648, 251) = 1
HCF of 977, 648, 251 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 977, 648, 251 is 1.
Highest Common Factor of 977,648,251 is 1
Step 1: Since 977 > 648, we apply the division lemma to 977 and 648, to get
977 = 648 x 1 + 329
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 329 and 648, to get
648 = 329 x 1 + 319
Step 3: We consider the new divisor 329 and the new remainder 319, and apply the division lemma to get
329 = 319 x 1 + 10
We consider the new divisor 319 and the new remainder 10,and apply the division lemma to get
319 = 10 x 31 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 648 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(319,10) = HCF(329,319) = HCF(648,329) = HCF(977,648) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 251 > 1, we apply the division lemma to 251 and 1, to get
251 = 1 x 251 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 251 is 1
Notice that 1 = HCF(251,1) .
