Given numbers are 546, 121, 570, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 121) = 66066
GCD(546, 121) = ( 546 x 121 ) / 66066
= 546 / 121
= 546
Step2:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 546, 121, 570, 257 is 1
