Given numbers are 571, 562, 28, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(571, 562) = 320902
GCD(571, 562) = ( 571 x 562 ) / 320902
= 571 / 562
= 571
Step2:
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
= 1 / 28
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 571, 562, 28, 139 is 1
