Given numbers are 190, 161, 670, 690
The list of prime factors of all numbers are
Prime factors of 190 are 2 x 5 x 19
Prime factors of 161 are 7 x 23
Prime factors of 670 are 2 x 5 x 67
Prime factors of 690 are 2 x 3 x 5 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 190, 161, 670, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(190, 161) = 30590
GCD(190, 161) = ( 190 x 161 ) / 30590
= 190 / 161
= 190
Step2:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 190, 161, 670, 690 is 1
