Given numbers are 646, 407, 579, 887
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 407) = 262922
GCD(646, 407) = ( 646 x 407 ) / 262922
= 646 / 407
= 646
Step2:
LCM(1, 579) = 579
GCD(1, 579) = ( 1 x 579 ) / 579
= 1 / 579
= 1
Step3:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
So, Greatest Common Divisor of 646, 407, 579, 887 is 1
