HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 725, 435, 389 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 725, 435, 389 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 725, 435, 389 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 725, 435, 389 is 1.
HCF(725, 435, 389) = 1
HCF of 725, 435, 389 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 725, 435, 389 is 1.
Highest Common Factor of 725,435,389 is 1
Step 1: Since 725 > 435, we apply the division lemma to 725 and 435, to get
725 = 435 x 1 + 290
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 290 and 435, to get
435 = 290 x 1 + 145
Step 3: We consider the new divisor 290 and the new remainder 145, and apply the division lemma to get
290 = 145 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 145, the HCF of 725 and 435 is 145
Notice that 145 = HCF(290,145) = HCF(435,290) = HCF(725,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 389 > 145, we apply the division lemma to 389 and 145, to get
389 = 145 x 2 + 99
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 99 and 145, to get
145 = 99 x 1 + 46
Step 3: We consider the new divisor 99 and the new remainder 46, and apply the division lemma to get
99 = 46 x 2 + 7
We consider the new divisor 46 and the new remainder 7,and apply the division lemma to get
46 = 7 x 6 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 145 and 389 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(46,7) = HCF(99,46) = HCF(145,99) = HCF(389,145) .
