GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 918) = 621486
GCD(677, 918) = ( 677 x 918 ) / 621486
= 677 / 918
= 677
Step2:
LCM(1, 759) = 759
GCD(1, 759) = ( 1 x 759 ) / 759
= 1 / 759
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 677, 918, 759, 642 is 1
