Given numbers are 640, 838, 159, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 838) = 268160
GCD(640, 838) = ( 640 x 838 ) / 268160
= 640 / 838
= 640
Step2:
LCM(2, 159) = 318
GCD(2, 159) = ( 2 x 159 ) / 318
= 2 / 159
= 2
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 640, 838, 159, 193 is 1
