Given numbers are 178, 257, 478, 535
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(178, 257) = 45746
GCD(178, 257) = ( 178 x 257 ) / 45746
= 178 / 257
= 178
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 535) = 535
GCD(1, 535) = ( 1 x 535 ) / 535
= 1 / 535
= 1
So, Greatest Common Divisor of 178, 257, 478, 535 is 1
