HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 156, 903 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 156, 903 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 768, 156, 903 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 768, 156, 903 is 3.
HCF(768, 156, 903) = 3
HCF of 768, 156, 903 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 156, 903 is 3.
Highest Common Factor of 768,156,903 is 3
Step 1: Since 768 > 156, we apply the division lemma to 768 and 156, to get
768 = 156 x 4 + 144
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 144 and 156, to get
156 = 144 x 1 + 12
Step 3: We consider the new divisor 144 and the new remainder 12, and apply the division lemma to get
144 = 12 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 768 and 156 is 12
Notice that 12 = HCF(144,12) = HCF(156,144) = HCF(768,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 903 > 12, we apply the division lemma to 903 and 12, to get
903 = 12 x 75 + 3
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 3 and 12, to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 903 is 3
Notice that 3 = HCF(12,3) = HCF(903,12) .
