Given numbers are 684, 433, 705, 642
The list of prime factors of all numbers are
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 433 are 433
Prime factors of 705 are 3 x 5 x 47
Prime factors of 642 are 2 x 3 x 107
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 684, 433, 705, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 433) = 296172
GCD(684, 433) = ( 684 x 433 ) / 296172
= 684 / 433
= 684
Step2:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 684, 433, 705, 642 is 1
