Given numbers are 561, 176, 492, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 176) = 8976
GCD(561, 176) = ( 561 x 176 ) / 8976
= 561 / 176
= 561
Step2:
LCM(11, 492) = 5412
GCD(11, 492) = ( 11 x 492 ) / 5412
= 11 / 492
= 11
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 561, 176, 492, 278 is 1
