HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 964, 916, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 42, 964, 916, 727 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 42, 964, 916, 727 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 42, 964, 916, 727 is 1.
HCF(42, 964, 916, 727) = 1
HCF of 42, 964, 916, 727 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 42, 964, 916, 727 is 1.
Highest Common Factor of 42,964,916,727 is 1
Step 1: Since 964 > 42, we apply the division lemma to 964 and 42, to get
964 = 42 x 22 + 40
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 40 and 42, to get
42 = 40 x 1 + 2
Step 3: We consider the new divisor 40 and the new remainder 2, and apply the division lemma to get
40 = 2 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 42 and 964 is 2
Notice that 2 = HCF(40,2) = HCF(42,40) = HCF(964,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 916 > 2, we apply the division lemma to 916 and 2, to get
916 = 2 x 458 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 916 is 2
Notice that 2 = HCF(916,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 727 > 2, we apply the division lemma to 727 and 2, to get
727 = 2 x 363 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 727 is 1
Notice that 1 = HCF(2,1) = HCF(727,2) .
