HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 102, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 102, 486 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, 102, 486 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, 102, 486 is 1.
HCF(977, 102, 486) = 1
HCF of 977, 102, 486 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, 102, 486 is 1.
Highest Common Factor of 977,102,486 is 1
Step 1: Since 977 > 102, we apply the division lemma to 977 and 102, to get
977 = 102 x 9 + 59
Step 2: Since the reminder 102 ≠ 0, we apply division lemma to 59 and 102, to get
102 = 59 x 1 + 43
Step 3: We consider the new divisor 59 and the new remainder 43, and apply the division lemma to get
59 = 43 x 1 + 16
We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get
43 = 16 x 2 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 102 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(59,43) = HCF(102,59) = HCF(977,102) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 1, we apply the division lemma to 486 and 1, to get
486 = 1 x 486 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 486 is 1
Notice that 1 = HCF(486,1) .
