Given numbers are 143, 195, 642, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(143, 195) = 2145
GCD(143, 195) = ( 143 x 195 ) / 2145
= 143 / 195
= 143
Step2:
LCM(13, 642) = 8346
GCD(13, 642) = ( 13 x 642 ) / 8346
= 13 / 642
= 13
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 143, 195, 642, 558 is 1
