HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 950, 484, 42 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 950, 484, 42 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 985, 950, 484, 42 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 985, 950, 484, 42 is 1.
HCF(985, 950, 484, 42) = 1
HCF of 985, 950, 484, 42 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 950, 484, 42 is 1.
Highest Common Factor of 985,950,484,42 is 1
Step 1: Since 985 > 950, we apply the division lemma to 985 and 950, to get
985 = 950 x 1 + 35
Step 2: Since the reminder 950 ≠ 0, we apply division lemma to 35 and 950, to get
950 = 35 x 27 + 5
Step 3: We consider the new divisor 35 and the new remainder 5, and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 985 and 950 is 5
Notice that 5 = HCF(35,5) = HCF(950,35) = HCF(985,950) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 484 > 5, we apply the division lemma to 484 and 5, to get
484 = 5 x 96 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 484 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(484,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
