HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 425, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 425, 189 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 765, 425, 189 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 765, 425, 189 is 1.
HCF(765, 425, 189) = 1
HCF of 765, 425, 189 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 425, 189 is 1.
Highest Common Factor of 765,425,189 is 1
Step 1: Since 765 > 425, we apply the division lemma to 765 and 425, to get
765 = 425 x 1 + 340
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 340 and 425, to get
425 = 340 x 1 + 85
Step 3: We consider the new divisor 340 and the new remainder 85, and apply the division lemma to get
340 = 85 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 85, the HCF of 765 and 425 is 85
Notice that 85 = HCF(340,85) = HCF(425,340) = HCF(765,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 85, we apply the division lemma to 189 and 85, to get
189 = 85 x 2 + 19
Step 2: Since the reminder 85 ≠ 0, we apply division lemma to 19 and 85, to get
85 = 19 x 4 + 9
Step 3: We consider the new divisor 19 and the new remainder 9, and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 85 and 189 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(85,19) = HCF(189,85) .
