HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 75, 70, 676, 249 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 75, 70, 676, 249 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 75, 70, 676, 249 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 75, 70, 676, 249 is 1.
HCF(75, 70, 676, 249) = 1
HCF of 75, 70, 676, 249 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 75, 70, 676, 249 is 1.
Highest Common Factor of 75,70,676,249 is 1
Step 1: Since 75 > 70, we apply the division lemma to 75 and 70, to get
75 = 70 x 1 + 5
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 5 and 70, to get
70 = 5 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 75 and 70 is 5
Notice that 5 = HCF(70,5) = HCF(75,70) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 676 > 5, we apply the division lemma to 676 and 5, to get
676 = 5 x 135 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 676 is 1
Notice that 1 = HCF(5,1) = HCF(676,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 249 > 1, we apply the division lemma to 249 and 1, to get
249 = 1 x 249 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 249 is 1
Notice that 1 = HCF(249,1) .
