HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 378 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 505, 378 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 505, 378 is 1.
HCF(505, 378) = 1
HCF of 505, 378 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 378 is 1.
Highest Common Factor of 505,378 is 1
Step 1: Since 505 > 378, we apply the division lemma to 505 and 378, to get
505 = 378 x 1 + 127
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 127 and 378, to get
378 = 127 x 2 + 124
Step 3: We consider the new divisor 127 and the new remainder 124, and apply the division lemma to get
127 = 124 x 1 + 3
We consider the new divisor 124 and the new remainder 3,and apply the division lemma to get
124 = 3 x 41 + 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 505 and 378 is 1
Notice that 1 = HCF(3,1) = HCF(124,3) = HCF(127,124) = HCF(378,127) = HCF(505,378) .
