Given numbers are 628, 404, 475, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 404) = 63428
GCD(628, 404) = ( 628 x 404 ) / 63428
= 628 / 404
= 628
Step2:
LCM(4, 475) = 1900
GCD(4, 475) = ( 4 x 475 ) / 1900
= 4 / 475
= 4
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 628, 404, 475, 143 is 1
