HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 117, 136, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 117, 136, 49 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 779, 117, 136, 49 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 779, 117, 136, 49 is 1.
HCF(779, 117, 136, 49) = 1
HCF of 779, 117, 136, 49 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 117, 136, 49 is 1.
Highest Common Factor of 779,117,136,49 is 1
Step 1: Since 779 > 117, we apply the division lemma to 779 and 117, to get
779 = 117 x 6 + 77
Step 2: Since the reminder 117 ≠ 0, we apply division lemma to 77 and 117, to get
117 = 77 x 1 + 40
Step 3: We consider the new divisor 77 and the new remainder 40, and apply the division lemma to get
77 = 40 x 1 + 37
We consider the new divisor 40 and the new remainder 37,and apply the division lemma to get
40 = 37 x 1 + 3
We consider the new divisor 37 and the new remainder 3,and apply the division lemma to get
37 = 3 x 12 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 117 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) = HCF(40,37) = HCF(77,40) = HCF(117,77) = HCF(779,117) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get
136 = 1 x 136 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1
Notice that 1 = HCF(136,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
