Given numbers are 678, 568, 671, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 568) = 192552
GCD(678, 568) = ( 678 x 568 ) / 192552
= 678 / 568
= 678
Step2:
LCM(2, 671) = 1342
GCD(2, 671) = ( 2 x 671 ) / 1342
= 2 / 671
= 2
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 678, 568, 671, 621 is 1
