HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 850, 750, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 42, 850, 750, 679 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 42, 850, 750, 679 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 42, 850, 750, 679 is 1.
HCF(42, 850, 750, 679) = 1
HCF of 42, 850, 750, 679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 42, 850, 750, 679 is 1.
Highest Common Factor of 42,850,750,679 is 1
Step 1: Since 850 > 42, we apply the division lemma to 850 and 42, to get
850 = 42 x 20 + 10
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 10 and 42, to get
42 = 10 x 4 + 2
Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 42 and 850 is 2
Notice that 2 = HCF(10,2) = HCF(42,10) = HCF(850,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 750 > 2, we apply the division lemma to 750 and 2, to get
750 = 2 x 375 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 750 is 2
Notice that 2 = HCF(750,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 679 > 2, we apply the division lemma to 679 and 2, to get
679 = 2 x 339 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 679 is 1
Notice that 1 = HCF(2,1) = HCF(679,2) .
