Given numbers are 861, 972, 137, 538
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 972) = 278964
GCD(861, 972) = ( 861 x 972 ) / 278964
= 861 / 972
= 861
Step2:
LCM(3, 137) = 411
GCD(3, 137) = ( 3 x 137 ) / 411
= 3 / 137
= 3
Step3:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
So, Greatest Common Divisor of 861, 972, 137, 538 is 1
