HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 770, 875 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 903, 770, 875 is 7 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 903, 770, 875 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 903, 770, 875 is 7.
HCF(903, 770, 875) = 7
HCF of 903, 770, 875 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 903, 770, 875 is 7.
Highest Common Factor of 903,770,875 is 7
Step 1: Since 903 > 770, we apply the division lemma to 903 and 770, to get
903 = 770 x 1 + 133
Step 2: Since the reminder 770 ≠ 0, we apply division lemma to 133 and 770, to get
770 = 133 x 5 + 105
Step 3: We consider the new divisor 133 and the new remainder 105, and apply the division lemma to get
133 = 105 x 1 + 28
We consider the new divisor 105 and the new remainder 28,and apply the division lemma to get
105 = 28 x 3 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 903 and 770 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(105,28) = HCF(133,105) = HCF(770,133) = HCF(903,770) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 875 > 7, we apply the division lemma to 875 and 7, to get
875 = 7 x 125 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 875 is 7
Notice that 7 = HCF(875,7) .
