HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 167, 779, 355, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 167, 779, 355, 641 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 167, 779, 355, 641 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 167, 779, 355, 641 is 1.
HCF(167, 779, 355, 641) = 1
HCF of 167, 779, 355, 641 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 167, 779, 355, 641 is 1.
Highest Common Factor of 167,779,355,641 is 1
Step 1: Since 779 > 167, we apply the division lemma to 779 and 167, to get
779 = 167 x 4 + 111
Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 111 and 167, to get
167 = 111 x 1 + 56
Step 3: We consider the new divisor 111 and the new remainder 56, and apply the division lemma to get
111 = 56 x 1 + 55
We consider the new divisor 56 and the new remainder 55,and apply the division lemma to get
56 = 55 x 1 + 1
We consider the new divisor 55 and the new remainder 1,and apply the division lemma to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 167 and 779 is 1
Notice that 1 = HCF(55,1) = HCF(56,55) = HCF(111,56) = HCF(167,111) = HCF(779,167) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 355 > 1, we apply the division lemma to 355 and 1, to get
355 = 1 x 355 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 355 is 1
Notice that 1 = HCF(355,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 641 > 1, we apply the division lemma to 641 and 1, to get
641 = 1 x 641 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1
Notice that 1 = HCF(641,1) .
