Given numbers are 621, 702, 455, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 702) = 16146
GCD(621, 702) = ( 621 x 702 ) / 16146
= 621 / 702
= 621
Step2:
LCM(27, 455) = 12285
GCD(27, 455) = ( 27 x 455 ) / 12285
= 27 / 455
= 27
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 621, 702, 455, 143 is 1
