HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 473, 680, 667, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 473, 680, 667, 155 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 473, 680, 667, 155 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 473, 680, 667, 155 is 1.
HCF(473, 680, 667, 155) = 1
HCF of 473, 680, 667, 155 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 473, 680, 667, 155 is 1.
Highest Common Factor of 473,680,667,155 is 1
Step 1: Since 680 > 473, we apply the division lemma to 680 and 473, to get
680 = 473 x 1 + 207
Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 207 and 473, to get
473 = 207 x 2 + 59
Step 3: We consider the new divisor 207 and the new remainder 59, and apply the division lemma to get
207 = 59 x 3 + 30
We consider the new divisor 59 and the new remainder 30,and apply the division lemma to get
59 = 30 x 1 + 29
We consider the new divisor 30 and the new remainder 29,and apply the division lemma to get
30 = 29 x 1 + 1
We consider the new divisor 29 and the new remainder 1,and apply the division lemma to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 473 and 680 is 1
Notice that 1 = HCF(29,1) = HCF(30,29) = HCF(59,30) = HCF(207,59) = HCF(473,207) = HCF(680,473) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 667 > 1, we apply the division lemma to 667 and 1, to get
667 = 1 x 667 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 667 is 1
Notice that 1 = HCF(667,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 1, we apply the division lemma to 155 and 1, to get
155 = 1 x 155 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 155 is 1
Notice that 1 = HCF(155,1) .
