Given numbers are 535, 644, 385, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(535, 644) = 344540
GCD(535, 644) = ( 535 x 644 ) / 344540
= 535 / 644
= 535
Step2:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
Step3:
LCM(1, 553) = 553
GCD(1, 553) = ( 1 x 553 ) / 553
= 1 / 553
= 1
So, Greatest Common Divisor of 535, 644, 385, 553 is 1
