HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 872, 756, 415 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 872, 756, 415 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 938, 872, 756, 415 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 938, 872, 756, 415 is 1.
HCF(938, 872, 756, 415) = 1
HCF of 938, 872, 756, 415 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 938, 872, 756, 415 is 1.
Highest Common Factor of 938,872,756,415 is 1
Step 1: Since 938 > 872, we apply the division lemma to 938 and 872, to get
938 = 872 x 1 + 66
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 66 and 872, to get
872 = 66 x 13 + 14
Step 3: We consider the new divisor 66 and the new remainder 14, and apply the division lemma to get
66 = 14 x 4 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 938 and 872 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(66,14) = HCF(872,66) = HCF(938,872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 2, we apply the division lemma to 756 and 2, to get
756 = 2 x 378 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 756 is 2
Notice that 2 = HCF(756,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 415 > 2, we apply the division lemma to 415 and 2, to get
415 = 2 x 207 + 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 415 is 1
Notice that 1 = HCF(2,1) = HCF(415,2) .
