Given numbers are 525, 781, 842, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(525, 781) = 410025
GCD(525, 781) = ( 525 x 781 ) / 410025
= 525 / 781
= 525
Step2:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 525, 781, 842, 142 is 1
