HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 475 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 378, 475 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 378, 475 is 1.
HCF(378, 475) = 1
HCF of 378, 475 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 475 is 1.
Highest Common Factor of 378,475 is 1
Step 1: Since 475 > 378, we apply the division lemma to 475 and 378, to get
475 = 378 x 1 + 97
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 97 and 378, to get
378 = 97 x 3 + 87
Step 3: We consider the new divisor 97 and the new remainder 87, and apply the division lemma to get
97 = 87 x 1 + 10
We consider the new divisor 87 and the new remainder 10,and apply the division lemma to get
87 = 10 x 8 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 378 and 475 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(87,10) = HCF(97,87) = HCF(378,97) = HCF(475,378) .
