Given numbers are 860, 398, 731, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 398) = 171140
GCD(860, 398) = ( 860 x 398 ) / 171140
= 860 / 398
= 860
Step2:
LCM(2, 731) = 1462
GCD(2, 731) = ( 2 x 731 ) / 1462
= 2 / 731
= 2
Step3:
LCM(1, 553) = 553
GCD(1, 553) = ( 1 x 553 ) / 553
= 1 / 553
= 1
So, Greatest Common Divisor of 860, 398, 731, 553 is 1
