Given numbers are 655, 781, 857, 463
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 781) = 511555
GCD(655, 781) = ( 655 x 781 ) / 511555
= 655 / 781
= 655
Step2:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
Step3:
LCM(1, 463) = 463
GCD(1, 463) = ( 1 x 463 ) / 463
= 1 / 463
= 1
So, Greatest Common Divisor of 655, 781, 857, 463 is 1
