Given numbers are 866, 782, 619, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(866, 782) = 338606
GCD(866, 782) = ( 866 x 782 ) / 338606
= 866 / 782
= 866
Step2:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 866, 782, 619, 557 is 1
