Given numbers are 545, 668, 221, 798
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 668) = 364060
GCD(545, 668) = ( 545 x 668 ) / 364060
= 545 / 668
= 545
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
So, Greatest Common Divisor of 545, 668, 221, 798 is 1
