Given numbers are 672, 538, 785, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 538) = 180768
GCD(672, 538) = ( 672 x 538 ) / 180768
= 672 / 538
= 672
Step2:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 672, 538, 785, 542 is 1
