Given numbers are 855, 661, 488, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 661) = 565155
GCD(855, 661) = ( 855 x 661 ) / 565155
= 855 / 661
= 855
Step2:
LCM(1, 488) = 488
GCD(1, 488) = ( 1 x 488 ) / 488
= 1 / 488
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 855, 661, 488, 147 is 1
