Given numbers are 129, 946, 507, 690

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

Apply this formula for all numbers.

Step1:

LCM(129, 946) = 2838

GCD(129, 946) = ( 129 x 946 ) / 2838

= 129 / 946

= 129

Step2:

LCM(43, 507) = 21801

GCD(43, 507) = ( 43 x 507 ) / 21801

= 43 / 507

= 43

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 129, 946, 507, 690 is 1
