HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 370, 962, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 370, 962, 780 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 671, 370, 962, 780 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 671, 370, 962, 780 is 1.
HCF(671, 370, 962, 780) = 1
HCF of 671, 370, 962, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 370, 962, 780 is 1.
Highest Common Factor of 671,370,962,780 is 1
Step 1: Since 671 > 370, we apply the division lemma to 671 and 370, to get
671 = 370 x 1 + 301
Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 301 and 370, to get
370 = 301 x 1 + 69
Step 3: We consider the new divisor 301 and the new remainder 69, and apply the division lemma to get
301 = 69 x 4 + 25
We consider the new divisor 69 and the new remainder 25,and apply the division lemma to get
69 = 25 x 2 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 370 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(69,25) = HCF(301,69) = HCF(370,301) = HCF(671,370) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 962 > 1, we apply the division lemma to 962 and 1, to get
962 = 1 x 962 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 962 is 1
Notice that 1 = HCF(962,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get
780 = 1 x 780 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1
Notice that 1 = HCF(780,1) .
