HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 778, 180 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 691, 778, 180 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 691, 778, 180 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 691, 778, 180 is 1.
HCF(691, 778, 180) = 1
HCF of 691, 778, 180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 691, 778, 180 is 1.
Highest Common Factor of 691,778,180 is 1
Step 1: Since 778 > 691, we apply the division lemma to 778 and 691, to get
778 = 691 x 1 + 87
Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 87 and 691, to get
691 = 87 x 7 + 82
Step 3: We consider the new divisor 87 and the new remainder 82, and apply the division lemma to get
87 = 82 x 1 + 5
We consider the new divisor 82 and the new remainder 5,and apply the division lemma to get
82 = 5 x 16 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 691 and 778 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(82,5) = HCF(87,82) = HCF(691,87) = HCF(778,691) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 180 > 1, we apply the division lemma to 180 and 1, to get
180 = 1 x 180 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 180 is 1
Notice that 1 = HCF(180,1) .
