HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 603 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 603 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 975, 603 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 975, 603 is 3.
HCF(975, 603) = 3
HCF of 975, 603 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 603 is 3.
Highest Common Factor of 975,603 is 3
Step 1: Since 975 > 603, we apply the division lemma to 975 and 603, to get
975 = 603 x 1 + 372
Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 372 and 603, to get
603 = 372 x 1 + 231
Step 3: We consider the new divisor 372 and the new remainder 231, and apply the division lemma to get
372 = 231 x 1 + 141
We consider the new divisor 231 and the new remainder 141,and apply the division lemma to get
231 = 141 x 1 + 90
We consider the new divisor 141 and the new remainder 90,and apply the division lemma to get
141 = 90 x 1 + 51
We consider the new divisor 90 and the new remainder 51,and apply the division lemma to get
90 = 51 x 1 + 39
We consider the new divisor 51 and the new remainder 39,and apply the division lemma to get
51 = 39 x 1 + 12
We consider the new divisor 39 and the new remainder 12,and apply the division lemma to get
39 = 12 x 3 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma 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 975 and 603 is 3
Notice that 3 = HCF(12,3) = HCF(39,12) = HCF(51,39) = HCF(90,51) = HCF(141,90) = HCF(231,141) = HCF(372,231) = HCF(603,372) = HCF(975,603) .
