HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 697, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 697, 727 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 425, 697, 727 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 425, 697, 727 is 1.
HCF(425, 697, 727) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 697, 727 is 1.
Step 1: Since 697 > 425, we apply the division lemma to 697 and 425, to get
697 = 425 x 1 + 272
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 272 and 425, to get
425 = 272 x 1 + 153
Step 3: We consider the new divisor 272 and the new remainder 153, and apply the division lemma to get
272 = 153 x 1 + 119
We consider the new divisor 153 and the new remainder 119,and apply the division lemma to get
153 = 119 x 1 + 34
We consider the new divisor 119 and the new remainder 34,and apply the division lemma to get
119 = 34 x 3 + 17
We consider the new divisor 34 and the new remainder 17,and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 425 and 697 is 17
Notice that 17 = HCF(34,17) = HCF(119,34) = HCF(153,119) = HCF(272,153) = HCF(425,272) = HCF(697,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 727 > 17, we apply the division lemma to 727 and 17, to get
727 = 17 x 42 + 13
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 13 and 17, to get
17 = 13 x 1 + 4
Step 3: We consider the new divisor 13 and the new remainder 4, and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 727 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(727,17) .
Here are some samples of HCF using Euclid's Algorithm calculations.
