HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 930, 603 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 930, 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, 930, 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, 930, 603 is 3.
HCF(975, 930, 603) = 3
HCF of 975, 930, 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, 930, 603 is 3.
Highest Common Factor of 975,930,603 is 3
Step 1: Since 975 > 930, we apply the division lemma to 975 and 930, to get
975 = 930 x 1 + 45
Step 2: Since the reminder 930 ≠ 0, we apply division lemma to 45 and 930, to get
930 = 45 x 20 + 30
Step 3: We consider the new divisor 45 and the new remainder 30, and apply the division lemma to get
45 = 30 x 1 + 15
We consider the new divisor 30 and the new remainder 15, and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 975 and 930 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(930,45) = HCF(975,930) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 603 > 15, we apply the division lemma to 603 and 15, to get
603 = 15 x 40 + 3
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 3 and 15, to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 15 and 603 is 3
Notice that 3 = HCF(15,3) = HCF(603,15) .
