Given numbers are 131, 698, 413, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(131, 698) = 91438
GCD(131, 698) = ( 131 x 698 ) / 91438
= 131 / 698
= 131
Step2:
LCM(1, 413) = 413
GCD(1, 413) = ( 1 x 413 ) / 413
= 1 / 413
= 1
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 131, 698, 413, 861 is 1
