Given numbers are 646, 636, 587, 918
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 636) = 205428
GCD(646, 636) = ( 646 x 636 ) / 205428
= 646 / 636
= 646
Step2:
LCM(2, 587) = 1174
GCD(2, 587) = ( 2 x 587 ) / 1174
= 2 / 587
= 2
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 646, 636, 587, 918 is 1
