HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 285, 783 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 195, 285, 783 is 3 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 195, 285, 783 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 195, 285, 783 is 3.
HCF(195, 285, 783) = 3
HCF of 195, 285, 783 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 195, 285, 783 is 3.
Highest Common Factor of 195,285,783 is 3
Step 1: Since 285 > 195, we apply the division lemma to 285 and 195, to get
285 = 195 x 1 + 90
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 90 and 195, to get
195 = 90 x 2 + 15
Step 3: We consider the new divisor 90 and the new remainder 15, and apply the division lemma to get
90 = 15 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 195 and 285 is 15
Notice that 15 = HCF(90,15) = HCF(195,90) = HCF(285,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 783 > 15, we apply the division lemma to 783 and 15, to get
783 = 15 x 52 + 3
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 3 and 15, to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 15 and 783 is 3
Notice that 3 = HCF(15,3) = HCF(783,15) .
