HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 844, 83, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 844, 83, 654 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 942, 844, 83, 654 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 942, 844, 83, 654 is 1.
HCF(942, 844, 83, 654) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 844, 83, 654 is 1.
Step 1: Since 942 > 844, we apply the division lemma to 942 and 844, to get
942 = 844 x 1 + 98
Step 2: Since the reminder 844 ≠ 0, we apply division lemma to 98 and 844, to get
844 = 98 x 8 + 60
Step 3: We consider the new divisor 98 and the new remainder 60, and apply the division lemma to get
98 = 60 x 1 + 38
We consider the new divisor 60 and the new remainder 38,and apply the division lemma to get
60 = 38 x 1 + 22
We consider the new divisor 38 and the new remainder 22,and apply the division lemma to get
38 = 22 x 1 + 16
We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get
22 = 16 x 1 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 942 and 844 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(38,22) = HCF(60,38) = HCF(98,60) = HCF(844,98) = HCF(942,844) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 83 > 2, we apply the division lemma to 83 and 2, to get
83 = 2 x 41 + 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 83 is 1
Notice that 1 = HCF(2,1) = HCF(83,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
