Given numbers are 143, 169, 691, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(143, 169) = 1859
GCD(143, 169) = ( 143 x 169 ) / 1859
= 143 / 169
= 143
Step2:
LCM(13, 691) = 8983
GCD(13, 691) = ( 13 x 691 ) / 8983
= 13 / 691
= 13
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 143, 169, 691, 545 is 1
