Given numbers are 621, 253, 666, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 253) = 6831
GCD(621, 253) = ( 621 x 253 ) / 6831
= 621 / 253
= 621
Step2:
LCM(23, 666) = 15318
GCD(23, 666) = ( 23 x 666 ) / 15318
= 23 / 666
= 23
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 621, 253, 666, 809 is 1
