Given numbers are 977, 821, 544, 142

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

Apply this formula for all numbers.

Step1:

LCM(977, 821) = 802117

GCD(977, 821) = ( 977 x 821 ) / 802117

= 977 / 821

= 977

Step2:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 977, 821, 544, 142 is 1
