HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 675, 505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 675, 505 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, 675, 505 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, 675, 505 is 1.
HCF(977, 675, 505) = 1
HCF of 977, 675, 505 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, 675, 505 is 1.
Highest Common Factor of 977,675,505 is 1
Step 1: Since 977 > 675, we apply the division lemma to 977 and 675, to get
977 = 675 x 1 + 302
Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 302 and 675, to get
675 = 302 x 2 + 71
Step 3: We consider the new divisor 302 and the new remainder 71, and apply the division lemma to get
302 = 71 x 4 + 18
We consider the new divisor 71 and the new remainder 18,and apply the division lemma to get
71 = 18 x 3 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 675 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(71,18) = HCF(302,71) = HCF(675,302) = HCF(977,675) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
