Given numbers are 812, 755, 254, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 755) = 613060
GCD(812, 755) = ( 812 x 755 ) / 613060
= 812 / 755
= 812
Step2:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 812, 755, 254, 621 is 1
