HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 619, 417, 964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 619, 417, 964 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, 619, 417, 964 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, 619, 417, 964 is 1.
HCF(977, 619, 417, 964) = 1
HCF of 977, 619, 417, 964 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, 619, 417, 964 is 1.
Highest Common Factor of 977,619,417,964 is 1
Step 1: Since 977 > 619, we apply the division lemma to 977 and 619, to get
977 = 619 x 1 + 358
Step 2: Since the reminder 619 ≠ 0, we apply division lemma to 358 and 619, to get
619 = 358 x 1 + 261
Step 3: We consider the new divisor 358 and the new remainder 261, and apply the division lemma to get
358 = 261 x 1 + 97
We consider the new divisor 261 and the new remainder 97,and apply the division lemma to get
261 = 97 x 2 + 67
We consider the new divisor 97 and the new remainder 67,and apply the division lemma to get
97 = 67 x 1 + 30
We consider the new divisor 67 and the new remainder 30,and apply the division lemma to get
67 = 30 x 2 + 7
We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get
30 = 7 x 4 + 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 977 and 619 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(67,30) = HCF(97,67) = HCF(261,97) = HCF(358,261) = HCF(619,358) = HCF(977,619) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 1, we apply the division lemma to 417 and 1, to get
417 = 1 x 417 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 417 is 1
Notice that 1 = HCF(417,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 964 > 1, we apply the division lemma to 964 and 1, to get
964 = 1 x 964 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 964 is 1
Notice that 1 = HCF(964,1) .
