Given numbers are 654, 492, 438, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 492) = 53628
GCD(654, 492) = ( 654 x 492 ) / 53628
= 654 / 492
= 654
Step2:
LCM(6, 438) = 438
GCD(6, 438) = ( 6 x 438 ) / 438
= 6 / 438
= 6
Step3:
LCM(6, 755) = 4530
GCD(6, 755) = ( 6 x 755 ) / 4530
= 6 / 755
= 6
So, Greatest Common Divisor of 654, 492, 438, 755 is 1
