Given numbers are 253, 338, 487, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 338) = 85514
GCD(253, 338) = ( 253 x 338 ) / 85514
= 253 / 338
= 253
Step2:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 253, 338, 487, 478 is 1
