Given numbers are 380, 492, 639, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 492) = 46740
GCD(380, 492) = ( 380 x 492 ) / 46740
= 380 / 492
= 380
Step2:
LCM(4, 639) = 2556
GCD(4, 639) = ( 4 x 639 ) / 2556
= 4 / 639
= 4
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 380, 492, 639, 542 is 1
