HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 773, 560, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 773, 560, 668 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 773, 560, 668 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 773, 560, 668 is 1.
HCF(773, 560, 668) = 1
HCF of 773, 560, 668 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 773, 560, 668 is 1.
Highest Common Factor of 773,560,668 is 1
Step 1: Since 773 > 560, we apply the division lemma to 773 and 560, to get
773 = 560 x 1 + 213
Step 2: Since the reminder 560 ≠ 0, we apply division lemma to 213 and 560, to get
560 = 213 x 2 + 134
Step 3: We consider the new divisor 213 and the new remainder 134, and apply the division lemma to get
213 = 134 x 1 + 79
We consider the new divisor 134 and the new remainder 79,and apply the division lemma to get
134 = 79 x 1 + 55
We consider the new divisor 79 and the new remainder 55,and apply the division lemma to get
79 = 55 x 1 + 24
We consider the new divisor 55 and the new remainder 24,and apply the division lemma to get
55 = 24 x 2 + 7
We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get
24 = 7 x 3 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 773 and 560 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(55,24) = HCF(79,55) = HCF(134,79) = HCF(213,134) = HCF(560,213) = HCF(773,560) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 668 > 1, we apply the division lemma to 668 and 1, to get
668 = 1 x 668 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 668 is 1
Notice that 1 = HCF(668,1) .
