Given numbers are 124, 861, 553, 151

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(124, 861) = 106764

GCD(124, 861) = ( 124 x 861 ) / 106764

= 124 / 861

= 124

Step2:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 124, 861, 553, 151 is 1
