HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 124, 779, 670 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 124, 779, 670 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 124, 779, 670 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 124, 779, 670 is 1.
HCF(124, 779, 670) = 1
HCF of 124, 779, 670 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 124, 779, 670 is 1.
Highest Common Factor of 124,779,670 is 1
Step 1: Since 779 > 124, we apply the division lemma to 779 and 124, to get
779 = 124 x 6 + 35
Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 35 and 124, to get
124 = 35 x 3 + 19
Step 3: We consider the new divisor 35 and the new remainder 19, and apply the division lemma to get
35 = 19 x 1 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 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 124 and 779 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(35,19) = HCF(124,35) = HCF(779,124) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 670 > 1, we apply the division lemma to 670 and 1, to get
670 = 1 x 670 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 670 is 1
Notice that 1 = HCF(670,1) .
